[PLAT-14993] Clean out pg_data_11 dir on onprem node release/delete

Summary: There's a new pg_data_11 directory to prepare for pg15 migration which needs to be deleted

Test Plan:
Create an onprem univ with 2024.1, release node and verify this dir is deleted.

```
[yugabyte@sanketh-tf-instance-n4 ~]$ ls /storage
cores  pg_data  pg_data_11  ybc-data  yb-data
```

After both release instance & delete universe ops
```
[yugabyte@sanketh-tf-instance-n4 ~]$ ls /storage
cores  yb-data
```
