doc/rados/operations: Fix unordered list in health-checks.rst

Fix missing empty line before an unordered list that caused it to be
rendered wrong.

Also, the sentences in each list item start with a capital case letter
so add the missing full stop at the end.

+A network partition has occurred among Ceph Monitors. This health check is
+raised when one or more monitors detect that at least two Ceph Monitors have
+lost connectivity or reachability, based on their individual connection scores,
+which are frequently updated. This warning only appears when
+the cluster is provisioned with at least three Ceph Monitors and are using the
+``connectivity`` election strategy.
+
+Network partitions are reported in two ways:
+
+- As location-level netsplits (e.g., "Netsplit detected between dc1 and dc2") when
+  all monitors in one location cannot communicate with all monitors in another location.
+- As individual monitor netsplits (e.g., "Netsplit detected between mon.a and mon.d")
+  when only specific monitors are disconnected across locations.
+
+The system prioritizes reporting at the highest topology level (``datacenter``, ``rack``, etc.)
+when possible, to better help operators identify infrastructure-level network issues.
