Thanks for working on this! CI is red with a reference to googleapis. Maybe we need to add a dep?

@fmeum I also had to update google.golang.org/genproto and also ran bazel run @io_bazel_rules_go//go -- mod tidy. CI is green now.

Do you happen to know whether these updates include any breaking changes (especially in protobuf)? I'm asking because an alternative approach that avoids a forceful update for users would be to document that contents of Go proto rules need to depend on a sufficiently recent protobuf version themselves.

I am not aware of any and Golang versioning requires breaking changes to become a new package (for example /v2).

Some of the packages are not yet at v1, but as users will have to update anyway at some point, I think we can risk it. If something breaks, we can always roll back. Thanks!
