[ops] meta: Add "version" graph

Description

Adds a simple graph for "version" as reported from server:

Note that cluster is not set in devstaging, but is in prod/staging, thus the label is a tad off. Cmp. prod:

Query: sum (gitpod_version_info{}) by (cluster, gitpod_version)

Just noticed the merge conflict 😬

Does it make sense to add this panel to the Server dashboard? I know that this is exposed by server, but maybe making a new dashboard "Meta Overview" would make more sense?

Not sure what to put in there besides the running version. Maybe also add each components version as well? Maybe some database metrics? 🤷 Just food for thought
