improve tool text description and args

[bhancockio]

Simplify tools for LLMs to better understand what they need to pass to tools.

Before

Tool Name: Read website content(**kwargs: Any) -> Any
Tool Description: Read website content(website_url: 'string') - A tool that can be used to read a website content. website_url: 'Mandatory website url to read the file'
Tool Arguments: {'name': FieldInfo(annotation=str, required=True), 'description': FieldInfo(annotation=str, required=False, default=''), 'args_schema': FieldInfo(annotation=type[BaseModel], required=True, description='The tool schema.', metadata=[SkipValidation()]), 'return_direct': FieldInfo(annotation=bool, required=False, default=False), 'verbose': FieldInfo(annotation=bool, required=False, default=False), 'callbacks': FieldInfo(annotation=Union[list[BaseCallbackHandler], BaseCallbackManager, NoneType], required=False, default=None, exclude=True), 'callback_manager': FieldInfo(annotation=Union[BaseCallbackManager, NoneType], required=False, default=None, description='.. deprecated:: 0.1.7 Use :meth:`~callbacks` instead.\n\nCallback manager to add to the run trace.', exclude=True), 'tags': FieldInfo(annotation=Union[list[str], NoneType], required=False, default=None), 'metadata': FieldInfo(annotation=Union[dict[str, Any], NoneType], required=False, default=None), 'handle_tool_error': FieldInfo(annotation=Union[bool, str, Callable[list, str], NoneType], required=False, default=False), 'handle_validation_error': FieldInfo(annotation=Union[bool, str, Callable[list, str], NoneType], required=False, default=False), 'response_format': FieldInfo(annotation=Literal['content', 'content_and_artifact'], required=False, default='content'), 'func': FieldInfo(annotation=Union[Callable[..., Any], NoneType], required=False, default=None), 'coroutine': FieldInfo(annotation=Union[Callable[..., Awaitable[Any]], NoneType], required=False, default=None)}
Tool Name: Search the internet(**kwargs: Any) -> Any
Tool Description: Search the internet(search_query: 'string') - A tool that can be used to search the internet with a search_query. search_query: 'Mandatory search query you want to use to search the internet'
Tool Arguments: {'name': FieldInfo(annotation=str, required=True), 'description': FieldInfo(annotation=str, required=False, default=''), 'args_schema': FieldInfo(annotation=type[BaseModel], required=True, description='The tool schema.', metadata=[SkipValidation()]), 'return_direct': FieldInfo(annotation=bool, required=False, default=False), 'verbose': FieldInfo(annotation=bool, required=False, default=False), 'callbacks': FieldInfo(annotation=Union[list[BaseCallbackHandler], BaseCallbackManager, NoneType], required=False, default=None, exclude=True), 'callback_manager': FieldInfo(annotation=Union[BaseCallbackManager, NoneType], required=False, default=None, description='.. deprecated:: 0.1.7 Use :meth:`~callbacks` instead.\n\nCallback manager to add to the run trace.', exclude=True), 'tags': FieldInfo(annotation=Union[list[str], NoneType], required=False, default=None), 'metadata': FieldInfo(annotation=Union[dict[str, Any], NoneType], required=False, default=None), 'handle_tool_error': FieldInfo(annotation=Union[bool, str, Callable[list, str], NoneType], required=False, default=False), 'handle_validation_error': FieldInfo(annotation=Union[bool, str, Callable[list, str], NoneType], required=False, default=False), 'response_format': FieldInfo(annotation=Literal['content', 'content_and_artifact'], required=False, default='content'), 'func': FieldInfo(annotation=Union[Callable[..., Any], NoneType], required=False, default=None), 'coroutine': FieldInfo(annotation=Union[Callable[..., Awaitable[Any]], NoneType], required=False, default=None)}

After

Tool Name: Search the internet
Tool Description: Search the internet(search_query: 'string') - A tool that can be used to search the internet with a search_query. search_query: 'Mandatory search query you want to use to search the internet'
Tool Arguments: {'search_query': {'description': 'Mandatory search query you want to use to search the internet', 'type': 'str'}}
Tool Name: Read website content
Tool Description: Read website content(website_url: 'string') - A tool that can be used to read a website content. website_url: 'Mandatory website url to read the file'
Tool Arguments: {'website_url': {'description': 'Mandatory website url to read the file', 'type': 'str'}}

Closes #1511
