fix: bg_roi_dilate in test suite ref doesn't match the actual case

[versey-sherry]

Issue being fixed or feature implemented

CI and pytest fail because the help value of --bg-roi-dilate in common_roi_options doesn't match the reference in test_click_param_annot in test_util.py.

help value of --bg-roi-dilate in common_roi_options was changed in https://github.com/dattalab/moseq2-extract/pull/130 but the related test was not changed.

What was done?

Change the ref dictionary in test_click_param_annot in test_util.py to match the updated help message.

How Has This Been Tested?

Locally and CI
