Dedupe translations

[silverwind]

We have many duplicate translations, for example:

$ rg '= Repository$' options/locale/locale_en-US.ini
51:repository = Repository
1883:settings.options = Repository
2075:settings.event_repository = Repository
2753:packages.repository = Repository
3117:notices.type_1 = Repository
3254:conan.details.repository = Repository
3407:runners.task_list.repository = Repository

We should deduplicate them, ideally without invalidating existing translation, if such a thing is possible. I do understand that some translations mean different things in different contexts, but I estimate 90% can be deduplicated safely.

Excerpt from #24492:

Other locales on main branch should not be updated manually as they will be overwritten with each sync

I imagine if we really want to start this deduping effort, it would be be nice to be able to just "move" a existing translation in all locales to a new key without invalidating on Crowdin.

Want me to add a check to make sure these files (other than English) are unchanged in a PR?

[silverwind]

Ideally we should have a way to modify other translations from this repo, e.g. making it a kind of two-way sync.

I currently don't understand enough of this sync process to further comment, but to cleanly solve this issue, we definitely need the ability to move around other language translations, and have those movements be accepted by Crowdin.

The plan ahead should be to:

• Remove all ini sections
• Merge all now-duplicate value strings from english translation
• Replicate the changes into other languages
• Force an approval of all translations from the ini on Crowdin

Is the last step possible? If not, we may never be able to clean this up properly.
