Update i18n read_path to match our current localization file layout (#15140)

* Update read path to match our current file layout

The files specified under "more files" were expecting to be
named *.{locale}.yml, like misc.en.yml or tags.fr.yml. However, our
project layout is using a directory prefix like misc/en.yml or
tags/fr.yml.

Consequently, the locale files for views were not being tested (a
previous update ensured that they were being loaded).

Change the load pattern to match the files we use in the app, and
ensure they're tested.

This introduces test failures which will be addressed in the next commit.

* Add back the original pattern

This matches files like devise.en.yml and other existing files in
config/locales (not already in a subdirectory).

* Update inconsistent interpolation

The english version had `{community}` while the french version had
`{name}` for the videos.heading key, checking the call site at
https://github.com/forem/forem/blob/main/app/views/videos/index.html.erb#L26
we have `community:`, passed for interpolation to the translate call,
so change the french translations to include that, rather than name

* Update missing pluralization for badges

* make travis happy
