Remove English English (en) translations
As on Control Center 1.1.0-RC1, we reset the language translation files, as the old ones had become invalid due the rewritten UI.
The build system is at the moment automatically generating only the base/template files, which are in English (en) and also a "en -> en" translation file, which is an exact copy of the template file contents (because it translates English to English).
This is unneeded, as all translation engines we use (go-text on the go code and vue-gettext) default to the base language (English in our case) when some translation is missing in other languages.
This also leads to misinformation on Weblate, that shows that the software is 100% translated, when it's not translated at all (0%), as it understands that English translation is 100% complete, which is always true by definition :-)
It also makes weblate trigger a warning that such file should be removed, as it's unneeded, as shown:
And:
Requirements:
- Delete the
po/en/LC_MESSAGES/webui.po
andpo/en/LC_MESSAGES/backend.po
files. - Prevent the build system of generating such files during build process.
- If needed, remove the English translations from weblate, in case they don't disappear automatically when we delete the files from the repository.
