Overview

Bumps project to Ruby 3.3.1

Contributors

If you used rbenv as suggested in our guides, you can update your local env with:

rbenv install 3.3.1
rbenv local 3.3.1 # or optionally, set it globally via `rbenv global 3.3.1`
bundle install

Misc

Aside from getting to the latest version of Ruby and Bundler, this also fixes:

• The devcontainer workaround from Fix devcontainer Dockerfile for Ruby 3.3.0 on Apple Silicon #293
• An issue with parser compatibility recently introduced by some Gemfile changes (explained here)

@robzolkos is this change in line with what you were expecting on the 3.3.1 release?

Until these are stable (follow up PRs coming), no reason to be running them as they are false negatives. Will reintroduce with more stability in the future.
