Height/integrity check fails for near resulting in no nodes being selected

[Andrew-Pohl]

Describe the Bug

When using an app staked for near in gateway server it fails to grab the block height with an invalid syntax error. Which then results in "cannot find source of truth for data integrity check" which means you get "Something went wrong node selector can't find node" when trying to send a relay.

My guess here is that it is due to near not confirming to jsonRPC spec.

Expected Behavior

Gateway server should be able to grab the block height of near in health checks

Steps to Reproduce

1. Stake an app with near
2. Launch gateway server with said app stake
3. Observe Logs for failed health/integrity check
4. Try sending a relay on 0052

Told by Dermot near isn't supported yet, suggested putting a "supported chains" section in docs. Happy to look at adding support for near to gateway server

[nodiesBlade]

The gateway server currently supports:

1. EVM chains that support eth_getBlockByNumber and eth_blockNumber (encapsulate majority if not all evm chains)
2. Solana
3. POKT

Given that Near RPC calls are slightly different and does not conform to the evm, this requires a special checkjob but should be possible with minimal code.
