Chore - Set dependabot ruby version #125
Description
Dependabot was failing on main due to the requirement of having vernier in the main Gemfile, but dependabot runs with an anciet ruby (2.7.X)
To avoid this, vernier is only added as a dependency if the ruby version is new enough:
But we added separate Gemfiles for legacy rubys and modern ones to avoid this exact problem.
It would be ideal to set the Ruby version used by dependabot somehow, since it seems to ignore .ruby-version.
