workaround: brew error in github action.

Fix the error:
```
==> Pouring python@3.11--3.11.5.monterey.bottle.tar.gz
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/2to3
Target /usr/local/bin/2to3
already exists. You may want to remove it:
  rm '/usr/local/bin/2to3'
```

Reference: https://github.com/universal-ctags/ctags/pull/3759

This is a workaround. When homebrew resumes working in github-action,
we need to revert this.
