display the `runs-on` macos platform in github action logs

[nikitakh-sure]

hi there,

i faced the issue with using the latest available stable Xcode 16.3 version, using the macos-latest as target platform to run on

after some tests i found the solution -- to change macos-latest target platform to macos-15

FEATURE SUGGESTION

would be great to see in logs what's the macos version the action's job is running:
