NE-2471: Remove feature-set annotations from Sail Library RBAC

Remove TechPreviewNoUpgrade annotations from Sail ClusterRole and
ClusterRoleBinding to enable Gateway API functionality on all clusters.

The CVO only includes TechPreview-annotated manifests in the payload
during cluster installation. When the feature set is changed on a
running cluster, the CVO restarts but uses the same pre-filtered
payload. This means TechPreview manifests are unavailable on clusters
installed with the Default feature set, even if TechPreviewNoUpgrade
is enabled later.

Without these annotations, the Sail Library RBAC will be included in
all cluster installations, allowing Gateway API to function correctly
as we promote the feature to GA.
