chore(site): edit GitHub links from hyper contrib documents (#90)

Populate a new page field 'hyper_path' for copied contrib files. Conditionally link back to hyper if a 'hyper_path' is present, otherwise continue to reference hyperium.github.io (relevant for all collections besides contrib).

Closes hyperium/hyper#3210
