Forc IPFS package fetching capabilities does not work with Pinata pinned packages

[kayagokalp]

Problem

We cannot use forc to fetch packages pinned by pinata. Pinata is a widely used pinning service making this limitation an important blocker in terms of reaching a working package registry and reduces the overall usability of IPFS support forc-pkg currently offers.

We are also planning to use pinata for package registry to make things a little bit easier. So it is for best if we solve this before going forward.
