Use relative aliases for all non-current Grafana aliases (#60062) 
* Use relative aliases for all non-current Grafana aliases

Prevents non-latest documentation "stealing" the page away from latest
and through permanent redirects for latest pages that no longer exist.

The redirected pages are indexed by search engines but our robots.txt
forbids them crawling the non-latest page.

Breaking changes

Fix No Data behaviour in Legacy Alerting

In Grafana 8.2.5 and later, this change fixes a bug in the evaluation of alert rules when using the AND operator to compare two or more conditions. In Grafana 8.2.4 and earlier such alert rules would evaluate to OK if at least one, but not all, conditions returned no data. This change fixes that bug such that in Grafana 8.2.5 these alert rules now evaluate to No Data.

If an alert should evaluate to OK when one or all conditions return No Data then this can be done via changing If no data or all values are null to OK. However, this will not preserve the old behaviour in 8.2.4 where an alert will be OK if at least one, but not all, conditions return no data and then No Data if all conditions return No Data.
