Generated Agda standard library HTML has no version information

NB - I found it (mildly) confusing that there is no version information (in the url) at
https://agda.github.io/agda-stdlib/Data.Product.Relation.Binary.Lex.Strict.html

I wonder how we can add version information to the generated HTML? Ideally we don't really want the URL to change every time we make a release as that would make linking a nightmare....

Well we already have

• http://agda.github.io/agda-stdlib/experimental/Data.Product.Relation.Binary.Lex.Strict.html

so we could have

• http://agda.github.io/agda-stdlib/main/Data.Product.Relation.Binary.Lex.Strict.html

under the same logic. It would be good to also get back to uploading the stable versions like we did for a while (e.g. v0.17)

and then http://agda.github.io/agda-stdlib/ could be a landing page listing
the various versions of the documentation available.

I was thinking of hackage: they have non-versioned URLs but they are being rewritten to the current version. e.g., try loading this in your browser:
https://hackage.haskell.org/package/ersatz/docs/Ersatz-Bit.html (for me, it actually visits https://hackage.haskell.org/package/ersatz-0.4.13/docs/Ersatz-Bit.html )
