A&R Enhancement -> Options in Add Subarea form should be sorted alphabetically

Scenario:
* Navigate to the A&R Admin on TEST environment: https://test-ar.bcparks.ca/
* Login as an Admin user
* Navigate to the Manage Subarea page
* Select a park, then check the subsequent fields options.

Expected:
* The options in dropdown fields should be sorted alphabetically

Issue:
* The options are not sorted and display in an random order in the following drop-down fields;
1. Region
2. Section
3. Bundle

Start by reproducing the issue on the Manage Subarea page in the TEST environment, then trace the Region, Section, and Bundle dropdown data in the Angular application. Confirm how each option list is built and verify that all three lists display in alphabetical order when done.
