harmonization of filter labels

Problem/Motivation

The labels of the media grid view are not the same as those of the media view.
Having the same labels improves legibility and maintainability.

If the label is modified in the view, the value is overwritten by the commands `drush locale:check` & `drush locale:update`

Proposed resolution

Update labels in views.view.media_library.yml

User interface changes
