The "SHOW HELP" button in the DAP2 Data Request Form points to a broken link

So, after some more thought, I agree that the best way to fix this is to get the www.opendap.org/online_help_files/opendap_form_help.html link to dereference to https://opendap.github.io/documentation/QuickStart.html#_an_easy_way_using_the_browser_based_opendap_server_dataset_access_form.

I looked at how that might work, but can't figure it out right away; Nathan asked Keith, I did too.
