Question: How to update `tests/mocks/JsonBindings.sol`?

[Wodann]

I've been trying to understand the developer workflow to update the tests/mocks/JsonBindings.sol file when changes are made to the tests/mocks/EIP712Types.sol file, but have been unsuccessful.

There are recent PRs that have successfully done so, but I cannot find any instructions in the README or codebase.

When I try to run forge bind-json in the root directory, the generated tests/mocks/JsonBindings.sol file does not include tests/mocks/EIP712Types.sol, rather I just get an empty JsonBindings:

// omitted lines for brevity

library JsonBindings {
  Vm constant vm = Vm(address(uint160(uint256(keccak256('hevm cheat code')))));
}

What command should I run and where to update the tests/mocks/JsonBindings.sol file?
