https://github.com/equinor/xtgeo/pull/1271 adds a work-around to make hdf5 installations from brew work when macOS is building, by causing brew to use the pkgconf package even though the GH Runner is imaged with pkg-config (deprecated).
Once the runner images have been updated to reflect this change we can remove the extra brew steps and should only need to keep brew install hdf5.
