Describe the problem you'd like to have solved

In the EXAMPLES.md it is stated that

provideAuth0 should never be provided to components, but only at the root level of your application.
Currently, nothing is preventing you to avoid it.

Describe the ideal solution

I propose to update the current code to using makeEnvironmentProviders (that has been created especially for this kind of requirements):

provideAuth0(config?: ...) {
    return makeEnvironmentProviders([...]);
}
