Update rubocop rspec

[baldarn]

rubocop rspec had a major update (version 3) and is splitting code for rails, capybara and factorybot

this pr moves on to version 3

there are lots of new rules.

I would suggest to update this and move update in our project. if needed, we can schedule the update with rubocop todo in each project
