Support versioning API along with docs

[rohit-gohri]

docusaurus docs have a version cli command that creates versioned docs.

We could implement folder auto-load support - #150
And then hook into the versioning flow or create equivalent CLI command that also versions the openapi folder

Initial discussion in PR - #339
Testing versioning - #338

+1 For Implementing this feature. This has been a lingering concern for us switching our API documentation from Slate to Docusaurus. I hope you all get this implemented. Just seeing that you all are looking to go in this direction, I am going to start porting our documentation over. We are not in a rush to version as we are currently in our first version but I think by the time we get to V2 you all should be rolling this out. Thanks for taking this feature into consideration and thanks @rohit-gohri for bringing it up.
