These were added to the Englisch docs in fastapi#10392.

I went through all instances of:

* docs/index.md
* docs/features.md
* docs/fastapi-people.md

in the rest of the docs and added this where missing. The PRs for the German translations (fastapi#10283, fastapi#10284, fastapi#10285) already contain this change.

I searched case sensitive under `./docs/`with the regex `!!! (?!tip|note|info|warning|danger|check)`.

Includes only the links where i just removed the `./` from the start and did nothing else.

I checked this and the links in the next commits with a script, see `linkchecker.py` in the `scripts/` commit in my workbranch (fastapi#10854). That script checks if local links (including images and python code files) are valid and well-formed. It also suggests hash parts of links that can possibly be translated.

Makes it simpler for translators to find a file.

Also contains one link (sql-databases.md) where the `./` is stripped from the start.

The linkchecker script helped me with these. I also checked each link manually.

Also applies the changes from the two previous commits to a few links.

Mkdocs complains about them.

Also apply changes from the previous four commits to some of them.

If I understand right, this is the format of such links.

Just a few, did not systematically check all.

Leads to a better overview.

No other file inks to them.
