RFR: 8361478: GHA: Use MSYS2 from GHA runners

[Aleksey Shipilev]

Installing MSYS2 takes considerable time in our Windows workflows. Fortunately, GHA runners currently ship with MSYS2 bundled! The docs for setup-msys2 step say it is enough to say `release: false` to use those:
 https://github.com/msys2/setup-msys2?tab=readme-ov-file#release

Also bumping the action version to gain access to the actual installed path.

Additional testing:
 - [x] GHA
