Version not shown anymore for self-hosted documentations

[GergelyKalmar]

Problem

We have a bunch of self-hosted documentation sites using the RTD theme. The version number used to be displaying fine below the project title (see e.g. https://docs.logikal.io/mindlab/latest/), however, this is not the case anymore with RTD theme v3. I understand that the version number has been replaced with the version selector, however, the version selector only works for sites hosted on readthedocs, effectively removing this information for self-hosted docs sites. There seems to be no way to switch back to the previous behavior.

Expected Results

We would like to have a config option to still show the version number instead of the version selector. Alternatively, the version selector should fall back to just displaying the current version when the Read the Docs Addon is not present.

If there's any workaround that we can apply in the meantime to get the version number back, that would be awesome.

Environment Info

• Python Version: 3.12
• Sphinx Version: 8.1.3
• RTD Theme Version: 3.0.1

I'm thinking that we may need to recover display_version and make it available only when READTHEDOCS == False. @agjohnson what are your thoughts here?

That seems reasonable, I would bring back what we had here previously and make sure it matches the previous styling/etc.
