Brew attempts and fails to install python on `macos-13` runners

Describe the bug

I see the following when using the action in a workflow that runs on: macos-13.

To Reproduce

I have not made an effort to reproduce this outside of the repo in which it is encountered, e.g. in a new/blank repo.

Expected behavior

Graphviz is installed.

Additional context

• Note that I am using the macos-skip-brew-update: true input.
• Previously I filed the similar Conflicts with r-lib/actions/setup-r on macOS #375. There, the work-around was to put the setup-graphviz step before setup-R. Here, this does not work.
• The workflow in question runs on macos-13 (x86_64 architecture), not macos-latest (arm64).

[khaeru]

For additional information, here is a workflow https://github.com/khaeru/genno/actions/runs/9559286674 in which this action is used with both macos-latest and macos-13 runners.

The jobs on macos-latest succeed; the ones on macos-13 fail. So I believe I am only seeing failures in the latter case and have updated the issue title.

Pending any fix, could a maintainer please let us know:

• Is this action intended to work on all GitHub's runner images, or only a subset? If so, which ones?
• Is it tested on macos-13?
