I18n for status search filter and mydspace.status badges not working

[mirkoscherf]

Describe the bug
Version 7.6

• The entries of the status search filter facet are currently not translatable
• The translation strings for status badges have changed, but only in en.json5

To Reproduce
(requires a repository with submitted items, demo7.dspace.org is fine)

1. Log in
2. Go to MyDSpace
3. Set language to English
4. Check 'Workflow tasks' and 'Your Submissions'
5. In the filter 'Status', the entries are available in English
6. The item status badges show English equivalents
7. Switch to another language (e.g. German)
8. Status filter entries and status badges still appear in English

Expected behavior
Status filter entries and status badges should be displayed in the set language.

Related work
#2068 changed localization strings for status badges, which were not changed in the other .json5 files.
