This PR generates a new helper function in the JS renderer that wraps isProgramError from @solana/programs such that, the error code type is known and the program address must not be provided.

Here's an example using the system program.

// Before.
isProgramError(error, txMessage, SYSTEM_PROGRAM_ADDRESS, SYSTEM_ERROR__ACCOUNT_ALREADY_IN_USE);

// After.
isSystemError(error, txMessage, SYSTEM_ERROR__ACCOUNT_ALREADY_IN_USE);

Here's another example without passing an explicit code expectation. For it to work with isProgramError a type parameter must be provided. With the generated helper, this is no longer needed.

// Before.
isProgramError<SystemError>(error, txMessage, SYSTEM_PROGRAM_ADDRESS);

// After.
isSystemError(error, txMessage);
