LG-5225 validation error IAL2

LG-5225 Validation Errors not shown in IAL2

Why:

• A good bug PR to get my hands dirty as a new dev on team ada
• Possible edge cases (disabling JS?) where this bug might still occur, but adding this line of code doesn't do any harm

How:

• Adding a flash[:error] in rails in the phone controller create function

Testing Instructions

1. Go to http://localhost:3000/verify
2. Create account, follow steps until you get to verify phone
3. In the developer tools DOM, edit <form> and add novalidate
4. Add a phone number that is not US (ie: 3065551234)
5. You should see the error as it appears in the screenshot below

Looks good! 👍

Optional depending if you're feeling up to it, but would be good to have some test coverage here as well, to make sure that the flash is set when the form is invalid.

identity-idp/spec/controllers/idv/phone_controller_spec.rb

Lines 132 to 133 in 522f388

	describe '#create' do
	context 'when form is invalid' do

LGTM 👍 You can safely disregard the GitLab build failure.
