Rename reCAPTCHA mock validator configuration, enable in review apps

[aduth]

🛠 Summary of changes

Renames the reCAPTCHA mock validator configuration name from phone_recaptcha_mock_validator to recaptcha_mock_validator, so that it can be reused for non-phone-specific mock validation. This also aligns to current usage in the otherwise-generic CaptchaSubmitButtonComponent.

It also enables mock validation in the review apps environments, to facilitate testing.

📜 Testing Plan

1. Go to TBD
2. Sign in or create an account
3. Add a phone to your account when presented the opportunity
   • From account dashboard: Click "Add phone number" in sidebar
   • From account creation: Choose "Text or voice message" from MFA selection
4. Observe field "reCAPTCHA score"
5. Enter a value above or below 0.5
6. Submit the page with an international phone number, e.g. +610491570006
7. Observe:
   • If you entered a value 0.5 or above, you are allowed to pass
   • Otherwise, observe you are shown an error message

Pretty sure this isn't configured in any deployed environments, but I'll double-check.

I checked all environments and there was one that needed to be updated (see Slack thread), but otherwise not overridden!
