Keycloak Should Always looks at default Institutions API for Account Creation

[kgudel]

When a user enters their email address the keycloak theme code sends a request to the institutions-api to get the list of institutions that are associated with that email domain.

That request is made here in the theme code.

This code is using the web domain that keycloak is currently on + /v2/public/institutions. This means that when you sign in for an account on ffiec.cfpb.gov it sends the request to ffiec.cfpb.gov/v2/public/institutions and if they are signing up on ffiec.beta.cfpb.gov it sends the request to ffiec.beta.cfpb.gov/v2/public/institutions.

However, the code should always send the request to the default (non-beta) site.
