Add a ci test for `offckb create`

[RetricSu]

Currently there is a integration test in the test.yml ci which will start pnpm start node and then curl the JSON RPC to make sure the devent is successfully launching. A similar ci test is required to make sure the offckb create command works fine on main platforms.

Note that to test the complete function of offckb create, you need to check the command implementations. And for integration test, you need to start a devnet node first using pnpm start node in the background and then create the boilerplate project(you might want to pass yes option to jump the confirm input on terminal) and doing build and deploy command to make sure the full workflow is good.

The test should be a bash script under scripts folder, similar to the previous node starting test.
