Fix icon in ee/app/assets/javascripts/users/identity_verification/components/verify_phone_verification_code.vue

The icon on line 192 is designed for use at size 16, it also looks like it should use the 'info' variant.

For more information look at the gl-icon storybook entry: https://gitlab-org.gitlab.io/gitlab-ui/?path=/docs/base-icon--docs
