[helm] Fix liveness/readiness probe scheme path in templates (#7616)

Fix the templates to read scheme from httpGet.scheme instead of the
probe level, matching the structure defined in values.yaml.

This ensures that changing *.livenessProbe.httpGet.scheme or
*.readinessProbe.httpGet.scheme in values.yaml now correctly affects
the rendered manifests.

Affected components: master, filer, volume, s3, all-in-one

Fixes #7615
