Suggested change

	tlsSecretVolume := corev1.Volume{
	Name: "proxy-tls-secret",
	VolumeSource: corev1.VolumeSource{
	Secret: &corev1.SecretVolumeSource{
	SecretName: rayclusterName + "-proxy-tls-secret",
	},
	},
	}
	// Patch to add new volume
	patches = append(patches, patchOperation{
	Op: "add",
	Path: "/spec/headGroupSpec/template/spec/volumes/-",
	Value: tlsSecretVolume,
	})

Missing the tls-secret volume for the Volume Mount
