fix: sync Helm chart RBAC with minimal CAPI Machine permissions

- Align Helm chart RBAC with config/rbac/role.yaml
- Reduce cluster.x-k8s.io permissions to read-only (get, list, watch)
- Remove unnecessary patch/update verbs on CAPI resources
- Add GitHub Pages configuration note to README for maintainers
- Fixes: controller crashes with 'cannot watch resource machines' error

fix: register Cluster API types in scheme

This fixes the crash on startup where the controller couldn't watch
Machine resources because v1beta1.Machine wasn't registered in the
runtime scheme.

Fixes: no kind is registered for the type v1beta1.Machine error
