ARR: Load custom PC webfield

[haroldrubio]

Depends on openreview/openreview-web#1897

This PR adds the submissionContentFields for papers flagged for desk reject verification. The tests set the flags on the tested submission to be false.

To flag a submission, submit an action editor or reviewer checklist and refer to the webfield to see what fields should be set to what value to make it flagged (ie setting Anonymity to "No")

You can make a desk reject verification reply to that submission's forum to test how it renders in the new tab

I'm getting the error Unhandled Runtime Error. TypeError: Cannot use 'in' operator to search for 'options' in undefined when I try to filter the Paper Status tab. Steps:

Using openreview-py test data:

• Go to http://localhost:3030/group?id=aclweb.org/ACL/ARR/2023/August/Program_Chairs#paper-status
• Click the Sort By dropdown

You should see the error. I don't see it in any of the other tabs.

I can reproduce the same issue, it seems to be related to the select widget, I'm not sure if the new tab is overriding some settings.

I found the error in how I was adding the content field to the sort options, I pushed a fix in web if you could take a look and review it
