Update french guide link

Update french guide link not accurate in README.md

Hmm, we had this on an external repo before and the repo went away. Maybe we could add it to the wiki of this repo instead? https://github.com/sabre-io/Baikal/wiki

@ByteHamster
At your convenience (feel free to copy the content into the wiki) but this guide is referenced in other places, I do not want to maintain it in several locations at the same time.

I do not plan to delete the content, but in the worst case scenario, the link will just be broken.

Opinions, @phil-davis? The person who owned the previous GitHub repo also said they don't plan to delete it, but still it's gone. Not sure if we want to officially support a guide in another language that we also didn't really fact-check.

The content looks reasonable, and still has links to the old repo. So that is a clue that it is the content that was in the old repo - good.

I made a PR to adjust those links: criticalsool/Baikal-Guide-FR#1

We should be better off having this new copy of the guide in French - might as well link to it. The alternative is to add these other-language guides to the Baikal repo itself, and ask people to make PRs when they want to correct/update them.

Thanks for the PR, regarding your alternative, it sounds interesting.
I could then delete my repository and reference the guide elsewhere directly from baikal.
That way, I'd be able to propose PR to the guide in baikal, furthermore, it would be easier for others to contribute than on my repository.

Choose what suits you best between that or leave it as a reference to my repository, I'll adapt.

@ByteHamster I suggest that you can merge this for now.
And then you can decide if you would like to add the content directly to the Baikal repo.

Thanks!
