Ignore brew dependencies for libraqm on macOS 13

[radarhere]

The macOS 13 GitHub Actions jobs have started failing - https://github.com/python-pillow/Pillow/actions/runs/9524124798/job/26256604583#step:7:150

==> Pouring libraqm--0.10.1.ventura.bottle.tar.gz
🍺 /usr/local/Cellar/libraqm/0.10.1: 12 files, 104KB
==> Caveats
==> jpeg
jpeg is keg-only, which means it was not symlinked into /usr/local,
because it conflicts with jpeg-turbo.

If you need to have jpeg first in your PATH, run:
echo 'export PATH="/usr/local/opt/jpeg/bin:$PATH"' >> /Users/runner/.bash_profile

For compilers to find jpeg you may need to set:
export LDFLAGS="-L/usr/local/opt/jpeg/lib"
export CPPFLAGS="-I/usr/local/opt/jpeg/include"

For pkg-config to find jpeg you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/jpeg/lib/pkgconfig"
Error: Process completed with exit code 1.

Ignoring the dependencies when installing libraqm resolves the error.
