Merge branch 'reprazent/gitlab-ce-bvl-find-correct-variables-for-testing-translations' into 'master'

Build correct variables for testing translations

Closes #48110

See merge request gitlab-org/gitlab-ce!32871

Start of fix for #21859, allow users to open files with newlines in the filenames.

Closes #21859

See merge request gitlab-org/gitlab-ce!32820

Add index on group_id column concurrently

See merge request gitlab-org/gitlab-ce!32826

This fixes previously added migration which caused timeouts on
big events table.

This makes sure we build the correct variables for testing
translations.

When translating, we could be specifying the variables in different
forms for each id:

- In the singular we could be using a `%{hash}` interpolation
- In the plural we could be using a `%d` interpolation

This changes the tests to accommodate for that: We now use the
variables used in the relevant translation id as the source for the
variables we mix in in specs.
