The about / FAQ page

- The address used there as an example does not use the clarin.de alias.
- I wonder how dynamic the backend version info is. Currently, the page says "BaseX 12.1", while, locally, we are playing with v. 12.3. So, if there is no way to query the DB version string dynamically, let's just say "v. 12.x"?
- Carefully check the page for other potential updates, perhaps another FAQ has surfaced?
