fix: Fetch actual path from gateway

[codynhat]

Description

In the event of a timeout from the IPFS node on raw.get, fetches the raw block of the actual leaf node from the gateway instead of the root. The fix is updated in js-geo-web.

Also updates the gateway to w3link.

Tried with a 20 items gallery and the performance is night and day relative to fetching the whole root. I did occasionally get 502 status code, don't know if it's a problem on my end, the server or else but it's something to keep in mind.
