BUG: Renovatebot has updated the test matrix to only test google provider >= 6.0

Renovatebot has updated the test matrix to only test google provider >= 6.0 which was not the original plan. The idea was that we would test multiple major versions of the google provider as we want to support all of our boilerplates which could be running version's 4.x, 5.x, or 6.x currently.

We need to unpick this and get back to running tests against these three versions of the provider.

Tagging @dkh21 for visibility as they merged the Renovatebot MR. Apologies, got confused, MR was merged by @rh841.
