    The Tcl/Tk version changed from 8.6.15 to 8.6.16 in the GH image.

    #127365 added the Homebrew tcl-tk@ pin to prevent Homebrew installing version 9.

    https://formulae.brew.sh/formula/tcl-tk@8 says it's also on 8.6.16.

    Perhaps we should try the --overwrite?

    That installs and passes:

    Linking /usr/local/Cellar/tcl-tk@8/8.6.15... 1753 symlinks created.

If you need to have this software first in your PATH instead consider running:
  echo 'export PATH="/usr/local/opt/tcl-tk@8/bin:$PATH"' >> /Users/runner/.bash_profile

    It might be worth temporarily disabling the job while this gets figured out. Many PRs are stuck because of this.
