Docker CI: should not display unknown as commit SHA and commit date

[curquiza]

Since v0.25.0 and the introduction of the new CI, MeiliSearch running on Docker does not display the commit sha and the commit date:

When building locally, I don't have any commit sha and date issue, they are well displayed at MeiliSearch launch.

@curquiza, after giving it a quick glance, it seems that this PR removes the use of env variables for building the image, in favor of importing the .git directory. But it seems that we you are still expecting to find these variables in the dockerfile here, and I see nowhere where the .git is actually copied. Not sure how all of that workds, but it may be worth to take a look at that.

I'm unable to reproduce the error for the latest version of meilisearch on dockerhub.

$ sudo docker run --rm -e MEILI_NO_ANALYTICS=true -p 770:770 getmeili/meilisearch:v0.30.0 ./meilisearch --master-
