Remove cookies before marshalling to privacy notice form

[allisonking]

Closes #3672

Description Of Changes

The privacy notice endpoint is strict about what fields get passed into its PUT. Since we added a cookies field recently, this was actually getting passed back into the endpoint, though it's not allowed. This PR adds cookies to the list of fields to remove before handling the form.

Code Changes

• Removes cookies from the form object
• Updates Cypress test so it will make sure we are only sending the values we expect

Steps to Confirm

• See issue steps

Pre-Merge Checklist

• All CI Pipelines Succeeded
• Issue Requirements are Met
• Update CHANGELOG.md
