Create a cypress test for l10n:

• switch the browser language to one of the supported languages other than english, load the ui
• check a couple of known strings are translated - pick so that we're testing at least one message from the API, and a couple of js t`` style and jsx <Trans> style translations (and if we have any plurals, that too)

• (optional) loop over `availableLanguages` , reload the ui and check the same message is translated (not english, not empty) and different (unique between available languages); to catch one laguage failing to load, or being a copy of another
• test fixed bug from https://issues.redhat.com/browse/AAH-1069 as well
