  Body: ## Upgrade `seleniumbase` to use the newer `selenium` (`4.23.1`)
  
  `selenium` `4.23.1` has been released.
  `selenium` `4.23.0` had a bug, which why `seleniumbase` `4.28.7` is still using `selenium` `4.22.0` (the previous version).
  Now it's safe to upgrade that dependency if all tests pass.
