Run of bundle update to update gems

[stevenwilliamson]

• Updates dependencies, i think all are development deps as the only non dev dep declared in the spec is mysql2
• Update docker image to debian as alpine failing
• Update to mysql8 for test image

All tests pass, however coverage appears down by a minor %, it's complaining that a single line in the spec file is not covered by tests which i don't fully understand
