Sean Arnold requested to merge readme-for-gemfiles into main Oct 03, 2023

Adds instructions for adding the Gem to a project that uses Gemfiles / Bundler.

Without this or another workaround as mentioned in gitlab-com/gl-infra/delivery#19695 (closed), the Gem will not be required properly in the application.
