Display when a repo was archived (#22664)

This adds the date a repo is archived to Gitea and shows it in the UI
and API. A feature, that GitHub has been [introduced
recently](https://github.blog/changelog/2022-11-23-repository-archive-date-now-shown-in-ui/).

I currently don't know how to correctly deal with the Date in the
template, as different languages have different ways of writing a date.
