Move commit and deployment time to a less prominent place in prod

[Bacluc]

Now with #4618 our users have a link to our blog,
which tells them more about the new features of ecamp than the commit hash and the deployment time.

Because of that, wen can remove the bottom bar, and move this information to a less prominent place for all environments (dev, staging and prod)
