fix: use eth_getBlockReceipts for Infura RPC kind

[MqllR]

Infura does provide support for eth_getBlockReceipts.

curl https://mainnet.infura.io/v3/xx \
         -X POST \
         -H "Content-Type: application/json" \
         -d '{"jsonrpc": "2.0", "method": "eth_getBlockReceipts", "params": ["latest"], "id": 1}'

I think you're right, but I am unable to check. The infura docs site is effectively down due to a redirect to metamask docs site, what a mess.

It will fallback automatically if the method is unavailable, so this is safe to merge.
Thanks
