Update Parsl to 2025.1.6

I am unable to recreate the recent CI failures (that are so consistent in CI!)
locally.  However, there was a major fix recently to be more clean during Parsl
shutdown, so I'm hoping this addresses the flakiness.  Let's see what happens!

+Changed
+^^^^^^^

+- Update Parsl to `2025.1.6 <https://pypi.org/project/parsl/2025.1.6/>`_.  Note
+  that Parsl's Channels were deprecated in Aug, 2024, and now completely
+  removed (see `Parsl Issue #3515
+  <https://github.com/Parsl/parsl/issues/3515>`_); consequently, this will be a
+  breaking change for those using Parsl's Channels.
