GH macOS builds are failing due to pkg-config install conflict

[kirkrodrigues]

Bug

Recent macOS builds are failing with the error below:

==> Pouring pkgconf--2.3.0_1.arm64_sonoma.bottle.tar.gz
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /opt/homebrew
Could not symlink bin/pkg-config
Target /opt/homebrew/bin/pkg-config
is a symlink belonging to [email protected]. You can unlink it:
  brew unlink [email protected]

To force the link and overwrite all conflicting files:
  brew link --overwrite pkgconf

To list all files that would be deleted:
  brew link --overwrite pkgconf --dry-run

Possible conflicting files are:
/opt/homebrew/bin/pkg-config -> /opt/homebrew/Cellar/[email protected]/0.29.2_3/bin/pkg-config
/opt/homebrew/share/aclocal/pkg.m4 -> /opt/homebrew/Cellar/[email protected]/0.29.2_3/share/aclocal/pkg.m4
/opt/homebrew/share/man/man1/pkg-config.1 -> /opt/homebrew/Cellar/[email protected]/0.29.2_3/share/man/man1/pkg-config.1
==> Summary
🍺  /opt/homebrew/Cellar/pkgconf/2.3.0_1: 27 files, 474.1KB
==> Caveats

It seems that the brew install of pkg-config now conflicts with the version of pkg-config that's already installed in the GH macOS hosted runner image.
