docs: add partition field for EBS

If the EBS volume is partitioned, you have to specify which partition to
mount or the mounting process will fail.

```
mount: /var/lib/kubelet/plugins/kubernetes.io/aws-ebs/mounts/vol-<volumeid>: wrong fs type, bad option, bad superblock on /dev/nvme3n1, missing codepage or helper program, or other error.
```
