DEICH-5562 replace modal for showing feeedback form with a regular link
The related issue details a bug where the modal doesn't always expand to show the whole form.
There's also complexities and security issues related to CSP because the content is served in an IFRAME from cognitoforms.com
The solution provided is simpler, cleaner and more secure. The only possible tradeoff is that it opens a new tab when then user clicks the link.
Closes #2021
