Add a reference to find the URL of the SRV record in Kubernetes

I closed the PR Create Scalar DL Backup and Restore Guide for Kubernetes to avoid redundancy.

README file of the scalar-admin contains the step for pause and unpause Ledger in Kubernetes.

I checked the following checklist with new changes.

Check if all requirements are met
Check if the goal has been achieved
Check if you understand what you are explaining perfectly
Check if all the sentences are clear, concise, easy-to-understand, and well-thought English
Make sure there are no spelling mistakes and grammatical errors
Make sure there is no redundancy
Make sure there is no inconsistency

A Guide on How to Backup and Restore Data in Scalar DL will help you create and restore a backup.
