Update foundry.mdx[Fix Foundry script]

Description

Adjust Foundry’s deploy and verify scripts to match the Telos EVM chain

The original deploy and verify scripts will prompt custom error: EIP-1559 not activated and ETHERSCAN_API_KEY must be set errors when executed, because the contract needs to be deployed on the Telos EVM chain, not Ethereum, so it is necessary to specify the Telos EVM corresponding verifier sourcify instead of the default etherscan;

In addition, perhaps Telos EVM does not yet support the EIP-1559 protocol, so it is necessary to specify the —legacy parameter to specify the transaction format before the London hard fork. Otherwise, it will prompt the EIP-1559 not activated error;

Test scenarios

The updated script passed the test, for example, this transaction is an example of a successful test: https://testnet.teloscan.io/tx/0x57e32321fb4e259dcc6b62b1b6c9788803f5e6a070b6e473cc4edec974fe75c9
