Retrieves the site revision ID.
The site revision ID is a unique identifier for the current revision of a site. Each time a site is manually saved or published following a change, a new revision is created.
You can view and manage a site's revisions in the Site History. You can use site monitoring to monitor and debug new revisions of a site.
Notes:
Since publishing a site may change the revision ID, the ID when previewing a site may be different than the ID for the published site.
The site revision ID is unique, but not meaningful. Therefore, you can't predict future revision IDs before they're created.
