Use username and password from shared config in call to login on @wordpress/e2e-test-utils

[rafaelzaleski]

Description

E2E tests fail in environments where the default username and password are not admin and password because these values are hardcoded in the login function. We need to use the values from the shared config (because they can be overridden in the env variables) instead of hardcode it in the login function.

Step-by-step reproduction instructions

1. Try to run tests in an E2E environment with the admin user username and password other than admin and password.
2. Call the login function from the issue description inside a test case.
3. There should be an error in your test case: Fetch api call failed for ${ apiFetch.nonceEndpoint }: ${ response.status }
