Add docs for lib bindings with supported library versions

[straight-shoota]

Adds documentation about which library versions are supported by the various lib bindings.

I'm planning to put that information on https://crystal-lang.org/reference/1.13/man/required_libraries.html as well. The URLs to this page should hopefully remind us to sync updates there.

Would be nice if we could leverage/improve https://github.com/crystal-lang/shards/blob/655a3b0fc416986dae1846ded3856aaf46198085/docs/shard.yml.adoc?plain=1#L176-L205 more to have this available in a more idiomatic way.

@Blacksmoke16 Yes, a structured format could be nice. But not sure how that would look like. A plain mapping between lib name and a version selector is not always sufficient.
So it's best to start with this and maybe figure out some more elaborate notation later.
