Refactor Agilent drivers

docs/changes/newsfragments/6089.improved_driver

@@ -0,0 +1,6 @@
+The Agilent drivers shipping with QCoDeS have been updated to ensure all Parameters are set as static
+attributes that are documented and can be type checked. The docs for the Agilent drivers have been
+updated to not document inherited members. This makes the documentation significantly more readable
+as it focuses on specific members for a given instrument. The documentation now also links superclasses.
+Please consult these for inherited members. It is the plan to make the same change to all drivers shipping
+with QCoDeS in the near future.
