You do not need a release. The action has a packages input and its default is tools platform-tools, which is the only reason your job asks for the dead one. Name what you want instead:

- uses: android-actions/setup-android@v4
  with:
    packages: 'platform-tools'

Green again on the next run.

Because it has been the default since before it was deprecated, and nothing broke while Google kept serving it. Defaults are only load bearing on the day the other side changes, which is also the day you find out what yours are.
