[PATCH v2] 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.
