Describe the feature you'd like to request

Describe the solution you'd like to see

Nextra doesn't support this out-of-the-box yet: shuding/nextra#20 :/

(note: Docusaurus and some others do - just as note here, i'm not proposing to migrate :))

I agree, having versioning for docs would be helpful, especially considering the upcoming small breaking change in the v2 SDKs. However, migrating away from Nextra is currently too big of a lift. Hope this will soon be included in Nextra.
