Ruby version support?

[olleolleolle]

Would it be time to update the CI matrix to in-support Ruby versions?

(Current status: Ruby 2.5 is EOL.)

bold claim: people running on Ruby <= 2.4 still use AMS instead of Blueprinter since Blueprinter isn't around since that long.

I.e. we could drop:

• 2.2
• 2.3
• 2.4

and add:

• 2.6
• 2.7
• 3.0

Also, if we perform the benchmark for each Ruby version, the boolean flag for this can be removed, i.e. we can greatly simplify the CI script by using a test matrix (see the docs: https://circleci.com/blog/circleci-matrix-jobs/).

... bundle install could also be cached... ^^

This is being addressed in #307. We are switching to GitHub Actions and moving to maintained ruby versions. 2.7 will be handled separately for known legacy application.

New 0.26.0 version has been released that is 2.7+
