Display snapshot settings on cPanel snapshot page

The cPanel snapshot page currently shows the following text:

A snapshot is a full account backup initiated at a specific point in time. A snapshot does not use your cPanel account disk space as it is stored on your hosting provider's backup storage destination. It is highly recommended to initiate a snapshot of your account before you make any major updates to your website. If your updates fail you can restore your website using a recently created snapshot of your account.

Add another sentence after that with something like the following:

You are allowed to have # snapshots that will be retained for # days. After that time the snapshot will be automatically removed.

The "#" placeholders will be replaced with the settings from the Settings/Snapshots.

This way cPanel users can easily see how many snapshots they are allowed and how long they will be retained.
