chore: fix cops with the wrong namespace

As part of the PR for adding support for Ruby 3.3 (airbnb#205) we bumped the
`rubocop-rspec` dependency to `~> 2.26`, which depends on
`rubocop-capybara` `~> 2.17` and `rubocop-factory_bot` `~> 2.22`. On
those versions, the `RSpec` namespace was removed from their cops hence
a warning was being logged when running `rubocop` with the last version
of this gem.
