types-protobuf overshadows google-cloud packages  #9267

Hi
The issue here is that the types-protobuf pakcage overshadows anything that google-cloud-* tried to export (by that I mean any google api package like google-cloud-bigquery or google-cloud-storage) which results in IDEs, language servers and all types of linters and type checkers failing even tho the code runs succesfully.

The issue is very simple to reproduce, simply install a package like google-cloud-bigquery and try to use it in your code.

When you open your IDE it will look something like this:

Tools like mypy or pylint will also not have a problem with that.

However if you install the types-protobuf package, which will be installed if you install types-all (that package is frequently installed in order for mypy to have type resolution for as many things as possible)m you will start getting errors like this (no matter the IDE):

Even tho the code will run succesfully.
I am not sure if this is the fault of the types-protobuf package or maybe the google packages export something in a bad manner. I am simply reporting this issue, I am making a twin report in googles api repo (googleapis/python-bigquery#1423).
