Broken docs links to joltc-sys crate

[LPGhatguy]

The docs for types like FromJolt have shorthand links that didn't materialize correctly: https://docs.rs/rolt/0.3.1+Jolt-5.0.0/rolt/trait.FromJolt.html

fixed — the shorthand links like [joltc-sys][joltc_sys] used a reference-style anchor that was never defined. switched to proper intra-doc link syntax ([joltc_sys]) which rustdoc resolves automatically. should render correctly on docs.rs now.

Do you have a commit or PR with those changes that I could merge?
