Require grpc 1.37 or newer
This changes the version pin on grpc to merely require the last known version we know to work well.
The fix in c7d5d95d
did not have the desired effect since ~>1.30
resolves
to ~>1.30.+
which still does not allow us to go
to version 1.4x.x
.
This change should address that problem.
I realized my mistake when trying to update grpc to 1.42.x
in gitlab (which was not available at the time); this currently fails with:
Bundler could not find compatible versions for gem "grpc":
In Gemfile:
grpc (~> 1.42.0.pre1)
gitlab-labkit (~> 0.21.1) was resolved to 0.21.1, which depends on
grpc (~> 1.30.2)
