Add loader, yarn, and api javadoc links
The loader javadoc is not yet up (waiting on FabricMC/fabric-loader#222). Unfortunately cannot request the linked url and remove link based on the request result (planned to remove links if the request result was 404 or so, but cannot do like cross-site requests for html)
This prob wont get merged in for a few reasons. I want to redo this version site and move it onto fabricmc.net I also want to supply a json file listing all the javadoc versions
Sure, I can redo the pr after like #4 is merged or so. However, I will make sure https://github.com/modmuss50/fabric-versions/pull/5/files#diff-a4271c53d2ad9d80a9ac6add8d5916c6R177 is applied because the current way you loop apparently causes some problem with js
Hmm, I still think this one would be worth it as it's hard to find version-specific links to the javadocs for api/loader/yarn otherwise.
