Update translations and remove crowdin reference.

[ElLorans]

Fixes #2633 and update translations.
TODO: remove https://crowdin.com/project/flask-admin since people are still working on it.

Can I ask where these translations are from? Have you done them yourself (personally Vs eg some machine translation)? Or pulled them from crowdin? 🙇‍♂️

[ElLorans]

Of course you can!
I translated them with google translate and or chagtgpt. The Italian, French and Spanish ones look correct to me, but I cannot vouch for the other ones. I can provide a Google calling googletransl() for all the additions, except the multiple plural form ones for which I used GPT.

I have squashed the commits. If machine translation is not enough, I can remove other languages except Italian. After we merge back mongoengine, we need to merge #2068 which makes Chinese translations more idiomatic (according to the author who is a Chinese speaker and to LLMs which provide the actual translation but when asked, say his translation is superior). Merging #2068 before restoring mongoengine is possible, but makes resolving conflicts useless since then we'll need the mongoengine translations back. Then, I'll do another pass at translations, if ok for you.

I'm going to take these on good faith 👀

Can we ask copilot to check?

[samuelhwilliams]

Yes, but I think that's still very much "good faith" 😅

Yes, but I think that's still very much "good faith" 😅

I'm happy to remove languages different from Italian, personally I need only that one. No offense taken, I understand your concerns.

• The translation for "Key" as "鑰匙" (physical key) is semantically incorrect in a software context. It should be "金鑰" or "鍵" to properly represent a data key/identifier.

msgstr "鑰匙"

flask_admin/translations/zh_Hant_TW/LC_MESSAGES/admin.po:335

• The translation for "Value" as "價值" (worth/price) is contextually incorrect. It should be "值" or "數值" to represent a data value in software context.

msgstr "價值"
