Enable rustdoc `generate-link-to-definition` feature on docs.rs (#5030)

You can see this feature in action
[here](https://docs.rs/sysinfo/latest/src/sysinfo/common/system.rs.html#46)
or on any of dtolnay's crates and many others. I found myself going
through your project code recently on docs.rs and I was a bit sad I
couldn't have this feature enabled. This should fix it at next release.
:)
