Temporarily disable CI for Windows with x64-mingw-ucrt

[andyw8]

Motivation

Recent changes in Bundler are causing the x64-mingw-ucrt platform to be removed, either when running running in Dependabot, or running bundle update --bundler locally. This breaks CI for Windows on Ruby 3.1 and newer.

Every Dependabot PR currently fails because of this, which is quite disruptive.

(I initially thought this was a Dependabot issue, so had opened dependabot/dependabot-core#8444).

I've tried various things to solve it, but wasn't able to yet yet. Since this a recent Bundler change, which will likely impact others too, I'm inclined to hold off doing more in case the behaviour gets reverted or altered. We can revisit this in a week or two.

Implementation

This PR disables CI for Windows where x64-mingw-ucrt is in use, and updates the Gemfile.lock as generated by bundle update --bundler.

Although disabling Windows does introduce some small risk, very little of Ruby LSP's behaviour is platform-dependent.

This is basically removing Windows entirely from CI. We can't do that or we risk getting into a replace where we push more Windows incompatible changes like we did in the past.

We should open an issue in rubygems asking if this is the new intended behaviour or a bug and ask for guidance on how to get CI passing.

As per Slack discussion, rubygems/rubygems#7172 may solve this but until then we'll manually run and commit bundle lock --add-platform x64-mingw-ucrt for Dependabot PRs.

Hey, just checking in. I see you having trouble with this and I could use help creating test cases.

If you could lock platforms that must stay available, what's the expected outcome? Would you use an optional group for the gems that won't work on windows?

Establishing expected behavior will help me get this in sooner.

Thank you!

P.S. look my first try at a test case at rubygems/rubygems#7195

Hi @martinemde, thanks for taking a look.

The platforms we need are:

arm64-darwin
x64-mingw-ucrt
x64-mingw32
x86_64-darwin
x86_64-linux

Adding the non-Windows gems sorbet-static-and-runtime and tapioca to an optional group should be possible.
