GGP-0040: Updated Feature Support (ens, arweave, 0.35.x)

Description

This GGP includes a proposed updated Feature Support Matrix including:

• Graph Node version to 0.35.0
  • Note: Past approval of GGP-0039: Delegation of responsibility for Graph Node version updates means the Council will stop ratifying the protocol-supported version of Graph Node to be used by Graph Indexers on the network and delegate such responsibility to the Graph Node team.
• Support for Arweave File Data Sources (at the same level as IPFS, given identical implementation and data isolation), supported as of Graph Node 0.33.0
• Full support for ENS:

  Missing rainbow tables now result in a non-deterministic error (graphprotocol/graph-node#4206). This is required, as a deterministic error would create a POI for the failure block and result in non-determinism vs. indexers who did have the rainbow tables present (who could keep syncing). A subgraph failing with a non-deterministic error doesn't generate a POI, and isn't eligible for indexing rewards - indexers could then import the rainbow tables, and as the failure is non-deterministic, it will be retried and syncing can begin again.

As with every new release, no POI divergences have been found after syncing ~100 subgraphs and comparing them against the previously ratified version.

Next steps

This PR will be closed pending Council approval.

Updated Feature Support Matrix

• Added a new subgraph feature: File data sources: Arweave with the same level of support of the previous File data sources: IPFS
• Updated the ENS feature to include support for Query Arbitration, Indexing Arbitration, and Indexing Rewards
