Adds Ruby 3.1 to the CI matrix. In addition to the minimal change to the CI configuration, the following additional changes are made to support the addition:
The version of the Rails in Gemfile and Gemfile.lock is updated from 7.0.0.rc1 to 7.0.2.2
Additional gem versions in Gemfile.lock are updated via bundle update
The CHANGELOG.md is updated to reflect the above
The 3.0 in the CI configuration is quoted, so that it properly resolves to a 3.0.x version. An unquoted 3.0 will be truncated to 3, causing it to load the latest Ruby 3 - at this time 3.1.1. To ensure a 3.0.x version is loaded we quote the 3.0.
