Add versioning support to `yazi`'s docs

Hello, I've experienced that deprecated features in the latest release can make it difficult to configure the nightly version. [Versioning](https://docusaurus.io/docs/versioning) of the docs would fix this issue. I'm also willing to contribute. I have not contributed to any projects before, so I might be slow in this. If I make a PR, would you be open to accepting it? As a project maintainer, Is this feature something you would want?
