chore(cli): Update cartesi-machine-stored-hash test case.

[brunomenezes]

Summary

This PR changes the test assertion for cartesi-machine-stored-hash cases to verify that a valid hash string is present, rather than asserting against a fixed hash value.

Because build environments can produce slight variations in the resulting output hash, strict hash comparison was causing test failures in CI/local environments—even when the dApp template code itself remained unchanged.

even when the dApp template code itself remained unchanged.

We should aim a reproducible build.

Isn't there any thing we can do to ensure this.

I am not sure, as from time to time we are changing the application-template Dockerfile, as it will eventually fail to build and updates are necessary. If I understood it right, the machine hash-generated factor, not just the code.
