Relax version specifier for 'google-protobuf' to fix build errors on Apple Silicon machines

[jazev-stripe]

Summary

This PR is a follow-up to #308 that relaxes the gem version constraint from a ~> major.minor.patch to a ~> major.minor constraint. This means that any 3.x version of google-protobuf is allowed, as long as the minor version is at least 3.19.

Doing so makes bundle resolve a much newer version of the grpc gem (on my machine, it makes it resolve 1.65.1 (released in July 2024) instead of 1.42.0 (released in Dec 2021)).

Motivation

The older grpc gem version 1.42.0 has a known issue that causes build failures on Apple Silicon macOS systems: grpc/grpc#35148. This is fixed in recent versions of the grpc gem.

By using a newer version of the grpc gem, fresh bundle installs on Apple Silicon computers work without any workarounds/special bundle/clang flags needed 🎉

Test plan

I ran a couple example bundle installs before/after the changes in this PR on my system. In between each run, I deleted the Gemfile.lock's, and then ran bundle clean --force with everything in the Gemfile temporarily commented-out (based on this approach). I also had to manually-reinstall rake and yard after doing so using gem install rake and gem install yard.

Without change in this PR

On a fresh run of bundle (with no lockfile) on my machine without this PR, I get the following resolutions followed by a clang build failure of the grpc gem's native components:

... a bunch of clang output and a single error ...

An error occurred while installing grpc (1.48.0), and Bundler cannot continue.

In Gemfile:
  temporal-ruby was resolved to 0.1.1, which depends on
    grpc

Note google-protobuf resolving to 3.19.6 and grpc resolving to 1.48.0.

Similarly, running bundle in the examples directory has a similar gem resolution/error.

Bundle complete! 7 Gemfile dependencies, 20 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.

Note google-protobuf resolving to 3.25.4 and grpc resolving to 1.65.1.

Similarly, running bundle in the examples directory now succeeds.
