Update the project page

Problem/Motivation

(note that only maintainers and content administrators can complete this task)

The Sitemap module's project page → is a bit outdated - in particular, at time-of-writing, it mentions Drupal 8 (which is no longer supported), and suggests that production sites use a release that is also no longer supported.

Proposed resolution

At the very least, we should update the part that recommends a release around the same time that we make a stable 8.x-2.0 release (see 🌱 [Plan] Stable 8.x-2.0 release Active ).

The module got a new README recently, in commit 6b584523, which should provide something for us to copy-and-paste.

When we're updating the project page, we should keep in mind the Project page template → as well.

Other things to consider are:

1. Maintenance status: should we be "Actively maintained" or "Minimally maintained"
2. Development status: should we be "Under active development" or "Maintenance fixes only"
3. Module categories: are these up-to-date? Some new categories have been added, and old ones retired recently

Remaining tasks

1. Propose new content
2. Review and feedback
3. RTBC and feedback
4. Update the page (a maintainer will need to do this)
5. Alternate text for the screenshot
6. Supporting organizations
7. Submission guidelines?
8. Custom issue summary template?
9. Is the documentation link(s) up-to-date?
