Ensure identity provider for downstream CRW projects should contain theme with username validation

[tolusha]

Is your task related to a problem? Please describe.

The different identity provide images are used for upstream and downstream projects. That's why changes introduced in #17265 are missed in CRW.

Describe the solution you'd like

The changes are quite simple, I guess it is possible update theme before keyckoask is started.

Additional context

#17265
