French translation for docs

[techknowlogick]

original PR go-gitea/docs#147 and author @0xBAADF00D

[lafriks]

I don't think we can keep it updated and it's better to not have translation than have outdated one but that's just my personal opinion.
At least while we don't have something like for web UI where we can keep them in sync

@lafriks I agree we probably won't be able to keep them in synch (unless we can use crowdin for something like this), but at least this will give us a head start until we get to that point.

Going through these with my (limited) french, they don't seem too out of date (well except the docker one, but at least those instructions still work). I'd need a person who actually speaks french to confirm this. The original PR is from august 23rd, and there are only 15ish commits to the docs since that time.

I'm ok either way (merging it, or not merging it) I just figured I'd give the option.

We could add a comment on header that indicate the recommended/updated docs is english ?

[techknowlogick]

@sapk that sounds like a good idea. I'm afraid my french ability doesn't allow me to write that sentence, would you be able to help?

[lunny]

So let's LGTM

[sapk]

Maybe update link?

[sapk]

@techknowlogick this could be done later.
LGTM for backporting.
