Pull #2750

github

Bump minimum required Ruby to 3.3

* `grape.gemspec`: `required_ruby_version = '>= 3.3'`.
* `.rubocop.yml`: `TargetRubyVersion: 3.3`.
* CI workflows: drop Ruby 3.2 from the `test` and `edge` matrices
  (and the now-empty `rails_edge` exclude entry).
* README install note and an UPGRADING entry for the contract break.
