#2933

Description (What does it do?)

Performs all the manual changes I've made on CI when working on the onboarding flow of new users. One caveat is that Organizations aren't yet supported in the Pulumi Keycloak provider, and so will require manual intervention initially.

Code Review

The pull request introduces changes to the Keycloak configuration, including enabling organization features, updating themes, configuring passwordless authentication, and defining roles and client scopes for the OL Data platform. These changes aim to streamline the onboarding process for new data platform users. The addition of passwordless authentication and role-based access control are significant improvements.

Merge Readiness

The changes introduced in this pull request appear to be well-structured and address the stated objective of streamlining the onboarding process for data platform users. However, due to the complexity of the changes and the lack of specific testing information, I am unable to fully assess the readiness for merging. I recommend that the author provide additional details on the testing performed, particularly around the new passwordless authentication flow and role-based access control configurations. I am unable to approve this pull request, and recommend that others review and approve this code before merging.
