Update lvms-scaling-storage-expand-pvc.adoc

- Needs to correct the command structure in Expanding a persistent volume claim.
- Here is the documentation link: https://docs.redhat.com/en/documentation/openshift_container_platform/4.16/html/storage/configuring-persistent-storage#lvms-scaling-expand-pvc_logical-volume-manager-storage

Here is the current documentation:

2. Update the value of the spec.resources.requests.storage field to a value that is greater than the current value by running the following command: 
~~~
$ oc patch pvc <pvc_name> -n <application_namespace> \ 
--type=merge -p \ '{ "spec": { "resources": { "requests": { "storage": "<desired_size>" }}}}' 
~~~

- In the above commands, the "- -" signs are incorrectly placed below the "$" symbol.
- However, they should be aligned parallel to the "oc" command, where the command begins.*

Here is the updated look:

2. Update the value of the spec.resources.requests.storage field to a value that is greater than the current value by running the following command: 
~~~
$ oc patch pvc <pvc_name> -n <application_namespace> \  1 
  --type=merge -p \ '{ "spec": { "resources": { "requests": { "storage": "<desired_size>" }}}}' 
~~~

- The commands will work as it is, but the structure is incorrect.
- It should be standard format all over the documentation.
- Hence it needs to be changed.
