Docs: Add documentation about Markdown editor features
What does this MR do?
Documents some features about the GitLab Markdown editor - the one present in issues, merge requests, and wiki pages.
The main purpose of this was to document new indenting behaviour introduced in !28914 (merged), but it felt too out-of-place, so I threw in docs about some other features as well:
- Preview (obvious)
- Formatting toolbar (obvious)
- Zen mode (?)
- Indenting (not obvious)
- Pasting images (not obvious)

Review checklist
All reviewers can help ensure accuracy, clarity, completeness, and adherence to the Documentation Guidelines and Style Guide.
1. Primary Reviewer
-
Review by a code reviewer or other selected colleague to confirm accuracy, clarity, and completeness. This can be skipped for minor fixes without substantive content changes.
2. Technical Writer
-
Optional: Technical writer review. If not requested for this MR, must be scheduled post-merge. To request for this MR, assign the writer listed for the applicable DevOps stage.
3. Maintainer
-
Review by assigned maintainer, who can always request/require the above reviews. Maintainer's review can occur before or after a technical writer review. -
Ensure a release milestone is set and that you merge the equivalent EE MR before the CE MR if both exist. -
If there has not been a technical writer review, create an issue for one using the Doc Review template.
