If the parameter doesn't start with Assistant:, it's returned unchanged, otherwise the prefix is removed.

At this writing, this template is not used by {{ASST}} or any of its (other) subtemplates. However, it seemed naturally to group prefix? and trim under the same template; and of the likely choices, {{ASST}} is both the shortest-named and most generic.
