adds envio as supported data indexer

[SvenMuller95]

waiting for issue kkrt-labs/kakarot-rpc#1333 to finish syncing Hypersync

[SvenMuller95]

This has been solved, and Hypersync has been fully onboarded onto Sepolia Testnet and is at chain head:

tl;dr

• Hypersync is automatically used in the indexer as a more performant data source than standard RPC for data retrieval (up to 1000 times faster). Standard RPC can still be used as well if desired (e.g. app with a small amount of data).
• Hypersync is a low-level API with clients in python, rust, nodejs, and go for data retrieval, and also comes with a RPC interface (for projects that have existing rpc code but want to increase their performance). Great for dapp building, analytics, explorers, wallets, etc.
