Improve pre-commit (dotnet, and remove a python warning)

[mikeage]

Use the system version of dotnet format instead of a pre-commit managed version. While this is normally not the best way to use pre-commit, it seems like everyone has it installed anyway, and this will let us use the latest versions without having to do ugly hacks like specifically inject v7.something

@andybak , can I ask you to try this PR locally (when you're back)?

Basically do the following:

git fetch --all -p
git checkout infra/precommit-dotnet
pre-commit run -a dotnet

And make sure it runs.

I think I finally figured out how to get rid of the ugly code to inject a specific version of dotnet-format. It works for me locally and it works in CI, so I'm hopeful....

Sorry typo in my instructions. It should have said dotnet-format

[andybak]

Oh - I should have spotted that myself!

[andybak]

Seems to work:

PS I:\Unity Projects\open-brush-main> pre-commit run -a dotnet-format
dotnet-format............................................................Passed

[andybak]

Just checked on my Macbook and that worked fine as well!

Excellent, thank you!
