No link to builds tab on crate page

[Nemo157]

E.g. https://docs.rs/crate/escargot/0.5.0 has no link to https://docs.rs/crate/escargot/0.5.0/builds, despite the latter having a "Builds" tab highlighted next to "Source".

I've actually discovered that there's another, more secretive tab. Squired deep in the cracks and crevices of Docs.rs, the author tab lurks. Some say it's never seen the light of day and that any mortal who gazes upon it will be driven mad by the brilliance of it
