Update dotnet-format to address breaking changes introduced by upstre…

…am changes (#5528)

Pre-commit is using a version of dotnet and dotnet-format and has picked up a newer version of the utility that is not compatible with .NET 3.1 or 5.x -- it installs it's packages using dotnet tool install. This version's default entrypoint is also incompatible with our project structure, as the style and analyzer subcommands are now run by default and do not support the --folder option.

The entrypoint can be over-ridden to specify the whitespace module, which should match previous behavior.
