Add bulk check permissions test

[tstirrat15]

Fixes #131

Description

There wasn't a test validating that check_bulk_permissions works, or example usage of check_bulk_permissions. This addresses the first and partially addresses the second.

Changes

• Add new test
• Add .ruby-version file for rvm etc
• Bump buf.gen.yaml to v2
• Bump some deps

Testing

Review. See that things pass.

running buf generate works for me. running the buf YAML file as a script throws an error. It worked when I added --template back

Failure: :2:1 unknown field "version", expected one of [file]
   2 | version: "v2"
   2 | ^

:3:1 unknown field "plugins", expected one of [file]
   3 | plugins:
   3 | ^

:8:1 unknown field "inputs", expected one of [file]
   8 | inputs:

Please add --template back to the buf yaml 🙏🏻
