chore: remove unused crd (#1855)

This CRD is left over un-used from the
#1735 PR.

## Summary by CodeRabbit

- Chores
- Removed the Settings CustomResourceDefinition from the distribution.
New installs and upgrades will no longer register or manage Settings
resources.
- Impact: Clusters will not create Settings resources, and any existing
ones may become unsupported. Review your configuration to ensure no
dependencies on the removed resource.
- Kustomization updated to exclude the Settings CRD from deployed
resources.
