pgsql: Fix a couple of wait event descriptions. - Mailing list pgsql-committers

Fix a couple of wait event descriptions.

The descriptions for ProcArrayGroupUpdate and XactGroupUpdate claim
that these events mean we are waiting for the group leader "at end
of a parallel operation," but neither pertains to parallel
operations.  This commit reverts these descriptions to their
wording before commit 3048898e73, i.e., "end of a parallel
operation" is changed to "transaction end."
