fix: handling of gh deps in noir_wasm (#4499)

# Description

Github deps are directly added to the file manager, which causes them to
be missing the absolute path to the source file and only include the
extraction directory relative to the fm root directory. This caused the
path to the file to be formatted in an unexpected way and the compiler
to panic.
