Describe the bug

The check rule for the parameter "collection_name" of "flush" interface is not consistent with that of "create_collection" interface

when collection_name is "12-s", create collection reports error "f"Invalid collection name: {collection_name}. the first character of a collection name must be an underscore or letter: invalid parameter"

but flush( "12-s") reports "collection not found[database=default][collection=12-s]"

>>> milvus_client.create_collection(collection_name="12-s", dimension=8)
RPC error: [create_collection], <MilvusException: (code=1100, message=Invalid collection name: 12-s. the first character of a collection name must be an underscore or letter: invalid parameter)>, <Time:{'RPC start': '2024-11-15 16:14:50.873458', 'RPC error': '2024-11-15 16:14:50.898214'}>

Expected Behavior

The check rule for the parameter "collection_name" of "flush" interface is consistent with that of "create_collection" interface

Steps/Code To Reproduce behavior

from pymilvus import MilvusClient
milvus_client = MilvusClient()
milvus_client.create_collection(collection_name="12-s", dimension=8)
milvus_client.flush(collection_name="12-s")

Environment details

- Hardware/Softward conditions (OS, CPU, GPU, Memory):
- Method of installation (Docker, or from source):
- Milvus version (v0.3.1, or v0.4.0):  master-20241115-d1596297-amd64
- Pymilvus version: 2.5.0rc121
- Milvus configuration (Settings you made in `server_config.yaml`):

@binbinlv The 2 error messages are both reported by Milvus, which I think are reasonable. Because flush doesn't create a collection.
