Add translations

[thomiceli]

Hello!

Opengist now supports translations, fetched via key-value YAML files, with one file per language.

It is possible to add translations via Weblate here: https://tr.opengist.io/projects/_/opengist/

I will try a German translation in the next few days.
I've been very busy the last few days.

Thanks for the mult-language option.

I've added some Czech translations. I'll try to review some translations when I have the time.

Turkish translation contained some errors and untranslated strings. I've updated it.

I've completed the missing Simplified Chinese translations and have proofread and standardized each Simplified Chinese translation.

I've added complete Polish translations a few hours ago.
There were some words I couldn't translate as there is just no equivalent word in Polish, such as: commit, revision, fork, Passkey, gist, but I think I handled them naturally, like you would in a normal conversation.
Waiting for a merge, as I deployed Opengist for my school and a few minutes after the announcement I got complaints that people can't understand it.
By the way, thanks for the amazing project! This is the only self-hosted pastebin I found that has an actually good public feed! By the way, just 1 little suggestion: could there be some sort of indicator that the preview of the gist is cut off? Like a small line with 3 dots at the bottom? Because now it's misleading that the gist is only 10 lines long.

By the way is there a one/few/many plural mode for some Slavic languages?
For example (this means X likes):
1 polubienie
2 polubienia
3 polubienia
4 polubienia
5 polubień
6 polubień
...
and this repeats for every multiple of 10 except 11, 12, 13, 14.
