Add badges to docs
What
- Last item of the new badges implementation - meta https://gitlab.com/gitlab-org/gitlab-ce/issues/42631
- Follows https://gitlab.com/gitlab-org/gitlab-ce/issues/40350
- Add product tier badges to docs:
Why
To facilitate the comprehension of which feature is available in which tier.
Architecture
- CE docs: add them only once, valid for the entire page
- Combined docs (different tiers for each section of the doc): apply them with Kramdown custom classes.
What we need
Kramdown (https://gitlab.com/gitlab-com/gitlab-docs/issues/50)- Code implementation
- BE/FE Review
