Calling Firebase `validatePassword` outside of an Injection context

Is the running outside of injection context warning legitimate when using `validatePassword`?

My code:

```ts
import { EnvironmentInjector, inject, runInInjectionContext } from '@angular/core';
import { Auth, validatePassword } from '@angular/fire/auth';
import type { PasswordValidationStatus } from '@angular/fire/auth';
import type { AbstractControl, AsyncValidatorFn, ValidationErrors } from '@angular/forms';

import { getPasswordControlValue } from './util';

/**
* Validate against the Firebase Project Authentication Password Policy.
*
* Note: at this time there is no actual need for this because the policy only enforces length and
* other Validators already check for that. However it is nice to know how to do this.
*/
export const passwordFirebaseValidator = (): AsyncValidatorFn => {
const auth: Auth = inject(Auth);
const environmentInjector = inject(EnvironmentInjector);

return async (control: AbstractControl): Promise => {
const value = getPasswordControlValue(control);

// Like Validators.email, rely on Validators.required to check for blank passwords.
if (value == undefined) {
return null; // eslint-disable-line unicorn/no-null -- ValidatorFn returns null
}

const { passwordPolicy: _, ...status } = await runInInjectionContext(
environmentInjector,
async (): Promise => validatePassword(auth, value),
);

return status.isValid ? null : { firebasevalidator: status }; // eslint-disable-line unicorn/no-null
};
};
```

I added `EnvironmentInjector` and `runInInjectionContext` and that got rid of the warning, but is all this necessary? It would be nice if validation was simplier.

Comece pelo ponto de entrada validatePassword e pelo wrapper runInInjectionContext mostrado; em seguida, acompanhe como o AngularFire lida com a instância de Auth e o contexto de injeção. Determine se o aviso é esperado e se o wrapper é necessário; considera-se concluído quando o padrão correto de chamada estiver documentado ou a validação for simplificada sem o aviso.
