Upgrade minimum required Ruby to v3.1.2

I am considering this the correct minimum Ruby because it is the Ruby
which is available in Debian 12 (bookworm), which is current in January
2025.

* https://www.debian.org/releases/
* https://packages.debian.org/bookworm/ruby/

Additional changes:
* fixup README
  - fix RubyDoc link
  - update copyright to 2025
  - add link to Apache2 license
* add `logger` development dependency, which is needed by licence_finder
  and dropped in Ruby 3.5.
* remove the bundler development dependency, and always use the built-in
  bundler
* add rubocop excentions
  - rubocop-performance
  - rubocop-rake

Github Action script and CI updates:
* drop the unsupported Rubies and added 3.3, 3.4
* remove ruby version specification from the `coverage` step, because it
  should use the default/minimum Ruby specified in the `.ruby-version`
* update action/checkout step to v4
