macOS: swap docs & CI from pkg-config to pkgconf #31335

   Migrate the macOS build docs and CI from pkg-config to pkgconf. As the former now just redirects to the later.

   Upstream is currently mass-migrating its formula. i.e https://github.com/Homebrew/homebrew-core/pull/198317.

   Add a workaround for #31334.

6. doc: migrate from pkg-config to pkgconf in macOS build docs

   Brew has migrated to using the later:
   ```bash
   brew info pkg-config
   ==> pkgconf: stable 2.3.0 (bottled), HEAD
   Package compiler and linker metadata toolkit
   https://github.com/pkgconf/pkgconf
   ```

   Given that the CI is now working here, (and #31334 wasn’t one-off, it’s happening for all new pushes (i.e #29881)), have updated the commit message and PR description.

    Don’t have a valid Mac to test on but change looks very straightforward and is in a similar vane to the linked upstream change.

    Add a workaround for #31334.

    Sounds like a TODO? Why not “Fixes #31334”?
