This patch (which is now merged and included in >=1.62.0) just removes the requirement for the
legacy golang-github-golang-protobuf-1-5-dev dependency. This should fix dependency problems where
there was conflict between the 1-5 and 1-3 variations.

This error is due to outdated golang-google-genproto package, which itself is a whole other rabbit
hole (involving cyclical dependencies).
