Support google/protobuf 4 in googleapis/common-protos-php

[leongersen]

#7201 in this repository allows set the dependency for google/protobuf to ^v3.25.3||^4.26.1.

This is not reflected in the released package for googleapis/common-protos-php. The composer.json for that package still depends on google/protobuf ^3.6.1.

This was correct until this commit, which references #7554.

#7580 reports another issue with this merge, which was fixed in #7591.

Having a similar issue in my app, can't upgrade googleapis/common-protos-php to the latest versions because my app also requires google/protobuf:^4, and ^4 support seems to have dropped in the latest version

This is fixed in https://github.com/googleapis/google-cloud-php/pull/7648 and in version 4.8.3 of google/common-protos

thanks for reporting this!
