Fix test performance of \Drupal\Tests\config_translation\Functional\ConfigTranslationInstallTest

Conversion seems fine.

Added a question to the MR.

left a comment back but will post here also.

but would that be valid? My understanding of InstallerTestBase is that it mimics the act of doing an install, during that you can't pick specific modules

But maybe in a follow up we could add a setup method to InstallerTestBase for steps to do after install?

Committed/pushed to 11.x and cherry-picked to 10.2.x, thanks! I think the manual module installs here are fine.
