@cursor update the macos runner and create a PR for this issue

[cursor]

Here’s what was done:

Changes

• .github/workflows/test.yml: runs-on updated from macos-11 to macos-15 (current GitHub-hosted image; macos-11 is retired).
• Cache keys: macos-otp- → macos-15-otp- for the asdf cache restore/save so caches aren’t reused across the old and new images.

Git

• Committed on cursor/macos-runner-update-df0a and pushed to origin.

Pull request

• Draft PR: elixir-desktop/deployment#14

If you want the PR marked ready for review or prefer macos-14 for stability instead of 15, say which you want and we can adjust.
