Add Envio to developer tools and resources

[Jordy-Baby]

This adds Envio to the developer tools and resources list.

Envio is a high-performance indexing framework that turns smart contract events into a queryable GraphQL API. Its HyperIndex framework supports indexing any EVM chain out of the box, including Core, using your own RPC as the data source, with fully managed hosting on Envio Cloud or self-hosting.

Hey @MarryamZulfiqar @gr-akshaya, we'd love to have Envio listed here and I've kept it consistent with the existing providers. Let me know if you need anything else from my end.

For reference, here are Envio's performance benchmarks: https://docs.envio.dev/docs/HyperIndex/benchmarking?utm_source=coredao&utm_medium=partner-docs

Gentle bump on this one. No rush at all. If any tweak to the wording, formatting or placement would help it land, just say the word and we will turn it around quickly.
