fix: pass all tests that be written in deploy-cloudrun.test.ts. (#345)

Because `describe.only` was written in the `deploy-cloudrun.test.ts` file, all tests in that file did not pass.
Therefore, we changed `describe.only` to `describe`.

Also, the `expect` message was wrong when the `gcloud_component` argument had an incorrect value, so we fixed this.
