-  1) script - This is the original converter to evaluate scripts for successful responses.
-  2) miq_script - Define a duplicate but differently named script converter whose purpose is to
-  evaluate scripts for unsuccessful ajax responses.  jQuery 3.5.0 changed the behavior of the script
-  converter, replacing it with a no-op converter for scripts found in unsuccessful ajax responses.
-  Successful responses would continue to be evaluated as previously.

-  Due to this change starting in 3.5.0, we define a new type of script we can set as the dataType
-  so it's evaluated in the event of unsuccessful responses such as the SSO 401 unauthorized
-  issue we attempted to fix in #9410 and subsequently completed in #9426.
