RuboCop fails on newer Ruby versions - due to changes in RuboCop

[olleolleolle]

On Ruby 3.2, this was the result:

Run bundle exec rubocop --parallel --extra-details --display-style-guide
Error: The `RSpec/FactoryBot/ConsistentParenthesesStyle` cop has been moved to `FactoryBot/ConsistentParenthesesStyle`.
(obsolete configuration found in vendor/bundle/ruby/3.2.0/gems/gc_ruboconfig-3.6.2/rubocop.yml, please update it)
The `RSpec/FactoryBot/SyntaxMethods` cop has been moved to `FactoryBot/SyntaxMethods`.
(obsolete configuration found in vendor/bundle/ruby/3.2.0/gems/gc_ruboconfig-3.6.2/rubocop.yml, please update it)

On 2.6, all passed.

We probably wish to run it on the oldest-supported version, only.
