- the x64-mingw32 platform has been superseded by x64-mingw-ucrt
- the mingw-ucrt platform is present as of Windows 10, which was released 10 years ago in 2015 and all versions prior to 10 are end-of-life and 10 will be by mid October 2025
- newer rubies use the mingw-ucrt platform instead of the mingw32 platform, meaning using the deprecated platform can cause issues during gem installation

Resolver had internal logic to prioritize locked versions when sorting
versions, however part of it was not being actually hit because of how
unlocking worked in the resolver: a package was allow to be unlocked
when that was explicit requested or when the list of unlocks was empty.
That did not make a lot of sense and other cases were working because
the explicit list of unlocks was getting "artificially filled".

Now we consider a package unlocked when explicitly requested (`bundle
update <package>`), or when everything is being unlocked (`bundle
install` with no lockfile or `bundle update`).

This makes things simpler and gets the edge case added as a test case
working as expected.
