Remove unused language choices
## Problem There are several languages currently available in GitLab as a user preference, but their translation levels are between 0% and 2%. This kind of a "false" choice creates a disappointing experience for the user, as there is pretty much no change in the UI once it is selected. ## Solution We will remove these choices from the UI until they reach at least 10% translated strings. ### TODO - https://gitlab.com/gitlab-org/gitlab/-/merge_requests/38312 - [x] Make [the list](#the-list) of languages not available in the UI - [x] Update the [documentation](https://docs.gitlab.com/ee/development/i18n/externalization.html#adding-a-new-language) with the information that languages with less than 2% of translations won't be available in the UI. ### The List These languages have 2% translation levels or less and are currently available in the UI (the numbers in the parenthesis are the current number of users with this selection and that number represented as a % of the total number of users): * Filipino (2 - 0.00%) * Polish (1,435 - 0.03%) * Dutch (472 - 0.01%) * Indonesian (930 - 0.02%) * Czech (378 - 0.01%) * Bulgarian (37 - 0.00%) * Esperanto (25 - 0.00%) * Galician (27 - 0.00%)
