Stub the SfCommand spinner. Even if you plan to make no assertions, this will silence the output to keep your test results clean
Parameters
- sandbox: SinonSandbox
Returns {
    start: SinonStub<
        [action: string, status?: string, opts?: { stdout?: boolean }],
        void,
    >;
    stop: SinonStub<[msg?: string], void>;
}
Example
```
import { stubSpinner } from '@salesforce/sf-plugins-core';
let spinnerStubs: ReturnType<typeof stubSpinner>;

// inside your beforeEach, $$ is a SinonSandbox
spinnerStubs = stubSpinner($$.SANDBOX);

// inside some test
expect(spinnerStubs.callCount).equals(1);
```
