Editing markdown files directly in Gitea

If you ever want to modify a Markdown documentation file in Gitea, you
do not need to clone the repo, use command line Git, etc. – anyone who
has access can do this right in the Gitea web UI. Quick video on this:

If you have more complex formatting like tables, you can still edit them in
Gitea, but it may be easy to check out the repo and edit the file
locally in Typora.
