--frozen-lockfile is deprecated in yarn3

[w0ofy]

The action uses the --frozen-lockfile flag for the yarn install step, but that flag is deprecated in yarn@v3.2.1 — the yarn resolution step is failing when running the install steps on the merged commits (e.g. PR's commit merged with main).

Here is an example of the failure described above: https://github.com/bigwoof91/real-system/runs/8051667671?check_suite_focus=true

Could there be a way to optionally use the the new CLI flag, --immutable ?

Hello, we're in 2025 and this issue is still not addressed.

Yes, and it'll still be the case in 2030 if no one that has an issue with it can be bothered to land a PR. We're volunteers doing this in our spare time, none of us are directly paid to work on this stuff.

Don't come into repos asking "It's <current year>, why isn't this fixed?". It's incredibly rude.
