Fix a couple of wait event descriptions.

nathan-bossart · nathan-bossart · commit 5ff9b6b4d981 · 2024-08-20T13:43:20.000-05:00
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 3048898, i.e., "end of a parallel operation" is changed to "transaction end."
