Ensure all components have at least one sample configuration

[mx-psi]

This is a documentation requirement for alpha and above components.

Steps to do this:

1. Add an optional field on metadata.yaml that has the example configuration (possibly on a separate field). Make sure to:
   1. Render this field in the README of the component.
   2. Generate a test to ensure the example is valid.
2. Add this to all components (or to 'higher priority' components)
3. Mark this field as required (possibly with an allowlist if we are focusing only on 'high priority' components).
