Conversation
Snapshot and WAL files are backwards compatible since Memgraph 2.0; remove the claims that they aren't. Correct when WAL files are deleted, add rollback steps, and document recovery from a damaged WAL or snapshot file.

Description
Fixes durability claims that contradict how Memgraph behaves: snapshot and WAL files written by Memgraph 2.0 or later load in newer versions, so the "not compatible between versions" warnings are gone. Also corrects when WAL files are deleted, adds rollback steps to the upgrade guide, and adds recovery steps for a damaged WAL or snapshot file to the troubleshooting pages.
Product PR
None, docs-only change.
Also fixes the
data-durabilityand durability errors page descriptions, and fences theCREATE SNAPSHOTandSHOW SNAPSHOTSexamples ascypher, and splits the snapshot interval examples so the Enterprise CRON one is separate. The CRON example was* * 12 * * *(every second during hour 12); it's now0 0 12 * * *(daily at noon). Ran the Community examples on Memgraph 3.14.0; the CRON one needs the licensed CI run.
