Align MAX_SNAPSHOT_ENTRIES with Snapper retention (off-by-one) (#6175)

* Align MAX_SNAPSHOT_ENTRIES with Snapper retention

Snapper is configured with NUMBER_LIMIT="5", but limine-snapper-sync
also counts the freshly-created / currently-booted snapshot, so five
retained snapshots are reported as six entries and it warns on every
snapshot and update:

  Snapshot limit mismatch: 6 Snapper snapshots exceed configured
  MAX_SNAPSHOT_ENTRIES=5

Raise MAX_SNAPSHOT_ENTRIES to 6 (NUMBER_LIMIT + 1) so the boot-menu cap
and Snapper's retention agree and the off-by-one warning stops. (An
alternative is MAX_SNAPSHOT_ENTRIES=auto, which derives the cap from
Snapper directly; kept an explicit value here to preserve the existing
boot-menu limit.)
