Display additional version info the documentation page header

[kaishin]

As discussed with @daveverwer, the documentation page could help visitors quickly identify if they are looking at the latest version. I was made aware of the banner displayed in the older version pages, but the latest version lacks an equivalent affordance.

Potential Solutions

The simplest solution would be to include said info between parentheses in front of the version number in the header (ex. 0.4.3 (latest) or similar.

Something a bit fancier would be a label with a separate visual styling in front of the version handle.

Further Considerations

This same pattern could be used to add information about the latest pre-release version or default branches.

Thanks @kaishin! I think this is a good idea. We could consider a very subtle "lozenge" type badge, maybe? I mocked something up:

Doesn't need to look like that, but it's a possibility.

We should also consider whether we should label it here:

After thinking about it, for now I think just doing the "Latest" (and not the latest prerelease or default branch) is best.

I'd agree with that and I think the LATEST lozenge looks nice.

I like the badge mock! The contrast could be improved a bit by making the background darker.
