Subject: [PATCH] Fix RPC_URL mismatch in Foundry tutorial

## Fix inconsistent RPC environment variable name

The tutorial defines the RPC endpoint in `.env` as:

RPC_URL=https://rpc-gel-sepolia.inkonchain.com/

and the deployment command uses:

forge script ... --rpc-url $RPC_URL

However, the `foundry.toml` example referenced a different variable:

${INKSEPOLIA_RPC_URL}

Following the guide step-by-step would therefore create only `RPC_URL`,
causing the `foundry.toml` configuration to reference a non-existent
environment variable.

This PR makes the tutorial consistent by updating the `foundry.toml`
example to use `${RPC_URL}`.

Documentation-only change.
