backstage release v3.38.1

Fixed

• (agent-platform) Set an organization model as the default through agent-manager by @fiunchinho — On the page of an organization’s model, organization admins can use Set as default again, which moves the organization’s default to that model. A model whose key is missing opens the credential form first.
