sig create/update --soft-delete option documentation

[webtonize]

While investigating the options for preventing accidental loss of images through deletion, I noticed the --soft-delete option for az sig create and az sig update. The current explanation in the docs stating it enables soft-deletion with a retention period allowing recovery of items in the gallery seems to fit my needs. However I cannot find the necesarry related documentation on:

• The default retention period
• Configurability of the retention period
• How to restore soft-deleted items
• Generic description of the feature on the Compute Gallery service overview page.
