@shiqicao entry functions do accept generic type parameters.

I am sensing the issue is probably passing it by using the CLI, because I tried the same function using TS SDK and it worked fine as a workaround.

```auto
const tx = new TransactionBlock();

tx.moveCall({
    target: '{pkg_id}::test::test',
    typeArguments: ['u8'],
    arguments: [
        tx.pure('1', 'u8')
]
... proceed with signing & executing the transaction

```
