bugfix: fix find_many api server stub

[lostman]

Description

Fixes #1505.

The correct find_many extern signature can be found here:

https://github.com/FuelLabs/fuel-indexer/blob/fefbf2c1f8addb952bb78cb95f28ee2cee041d4e/packages/fuel-indexer-plugin/src/wasm.rs#L27C28-L27C72

Testing steps

Start fuel-indexer service and deploy an indexer:

cargo run -p fuel-indexer -- run --network beta-4 --replace-indexer

cargo run -p forc-index -- deploy --path examples/fuel-explorer/fuel-explorer/

On v0.24.2 it fails with an error:
