This commit adds `Binary` and `Git Formats` to the list of default packages.

1. sort urls alphabetically
2. reformat patterns to use more of available space
3. disallow `#` (start of anchors) and `?` (start of parameters)
   in user and repository names
4. move (?<!\.git) to ensure not to accept something like
   https://github.com/repo/user.git/tree/master

Now that arm64 is supported it is very valid to have both x32 and x64
to specify arm64 is not supported.

To support validation and completions via LSP-json, Package Control ships
json schemas for channels and repositories.

This commit allows them to be explicitly assigned without tests failing via
- "$schema": "sublime://packagecontrol.io/schemas/channel",
- "$schema": "sublime://packagecontrol.io/schemas/repository",

url and base keys are already handled some lines above.

... didn't match osx-arm64 before.
