Filter locales under 25%

[sapk]

This PR roughly does that by counting line on translation files.

The files that will be removed:

Removing ./options/locale/locale_lt-LT.ini: 290/551
Removing ./options/locale/locale_nb-NO.ini: 226/551
Removing ./options/locale/locale_nn-NO.ini: 123/551
Removing ./options/locale/locale_no-NO.ini: 161/551
Removing ./options/locale/locale_ru-UA.ini: 109/551
Removing ./options/locale/locale_vi-VN.ini: 123/551

I added a wip label because I scratch that on github but it need to be tested a little more.

Fix #9779

[lafriks]

We should also not show language in selection also than if no locale file exists for it

[sapk]
