Add Etherlink to the explorer contract import networks

[Jordy-Baby]

Tags Etherlink (42793) as NetworkWithExplorer alongside HypersyncChain, so it shows up in envio init contract-import explorer --blockchain.

It was tagged HypersyncChain only, so the CLI had no explorer import path for Etherlink while HyperSync indexing worked fine.

The backend already serves it after enviodev/ui#1199:

curl "https://envio.dev/api/hyperindex/contract-import?chain=42793&address=0x6Fb65D60B4Ae844C5f9fE6929403CeE652397195"

returns 200 with the contract name and ABI, so the enum tag was the only blocker.

Came up in etherlinkcom/docs#433 where Etherlink asked whether we index their chain.

Not compiled locally, there is no Rust toolchain on this machine. Nothing matches exhaustively on NetworkWithExplorer, so CI is the first real check.
