Fix collection-to-set conversion causing type mismatch in JCasC setters

[somiljain2006]

Fixes #2828

Fixes IllegalArgumentException when configuring collection-based attributes like disabledAdministrativeMonitors. Previously, it passed a List to setters expecting Set/SortedSet, causing a runtime type mismatch. This change converts collections to the appropriate type (LinkedHashSet or TreeSet) before invoking the setter.

Verified manually using mvn hpi:run with a configuration including disabledAdministrativeMonitors. Jenkins starts successfully, and the configuration is correctly applied and exported.
