docs: formatsnapshot: add docs for snapshotDeleteInProgress

Adds documentation for the <snapshotDeleteInProgress/> element to
the libvirt snapshot format XML reference. The <snapshotDeleteInProgress/>
element, introduced at commit 565bcb5d79, ensures the consistency of qcow2
images during snapshot deletion operations by marking disks in snapshot
metadata as invalid until deletion is successfully completed.

The commit was merged but the related documentation was missing.
