Add authorization header to Infura IPFS calls

[fselmo]

What was wrong?

Infura IPFS calls started requiring proper authentication as of 8/10/2022. We silenced these errors in order to have the tests passing but we need to add a proper authorization header to Infura IPFS calls.

v6 changes: #2603 v5 changes: #2605

How can it be fixed?

• Add proper authorization header with Infura project id and secret to Infura IPFS calls.
• See these commits for what to turn back on when proper authorization headers are added to these calls:
  • v6: 5aad062 and f75d604
  • v5: 5ab9c04

EthPM is deprecated and is the only thing that needs IPFS. Closing wontfix
