Documentation site lacks version selection

Summary

While reviewing documentation, after sometime away from Rust, I was surprise that the documentation site at https://doc.rust-lang.org/std/ did not provide a convenient means of selecting the Rust version for the documentation it provided. It did help display the Rust version of the documentation it was actually showing but a way to switch to an earlier version that was needed would have been nice. According to Google Gemini, I have to manually modify the URL to insert the correct Rust version, presumably in the correct format whatever that would be.

Correct. This is a fairly direct upload of the rustdoc, which itself has no knowledge that other versions exist (being built for one version). As we don't formally support the non-stable/beta/nightly versions, it's a somewhat curious case, as the question arises of whether we should. We could definitely offer a selector between the stable, beta, and nightly versions, assuming we addressed the other technical difficulties, though.

I am labeling this for T-rustdoc as though this could be fixed at another layer, I would like to hear their opinion on the matter.

as a point of info, docs.rs does this by using an HTML parser to rewrite the stream as it’s served: https://github.com/rust-lang/docs.rs/blob/b00825f86cf55b4d060e8b54db3b9d2c9611f881/src/utils/html.rs#L35
