Fixes for Keycloak 26.5

[tobiasge]

These are the changes I needed to run this plugin with the new Keycloak 26.5.

Thanks for this

Just FYI: this PR was released with Keycloak 26.5 (keycloak/keycloak#43963). As part of that change, IdentityProviderRepresentation.isLinkOnly() may now return null.

This plugin uses that method in an if statement in Redirector, which can lead to an NPE (see here).

It likely should be updated to use the newly introduced org.keycloak.util.Booleans.isTrue(...) helper in that condition, although I’m not 100% certain this is the intended behavior.

What about Keycloak's Organizations feature?
From what I see there, it can be used to achieve almost the same thing: Take the user's email, select the correct IDP and redirect there. I've already given it a small-scale test and it worked like a charm.

Can anyone confirm this as a viable alternative?
