Modify a line of code in test.rs

What version are you using?

22.0.1

What did you do?

Followed this tutorial https://developers.stellar.org/docs/build/smart-contracts/getting-started/hello-world.
Created test.rs using the init command as follows.

stellar contract init soroban-hello-world

Got an error in the 'Contract Unit Test' section, and then modified Line 9 in test.rs as follows.

let contract_id = env.register_contract(None, Contract);

After the modification, I got the same output as shown in the tutorial.
