The configuration of the `MonopoleLooperKiller` missed being updated
in the last update of the configuration syntax of `G4UserActions`.
This means that monopole simulation jobs fail in 21.0.37.
This commit updates the syntax such that the jobs should now succeed.
Should fix ATLASSIM-3440.

A number of different ways of configuring UserAction Tools were tried.
This merge request attempts to migrate all syntax to use simFlags.OptionalUserActionList
