Remove cred feedback url configurability (#991)

We added a configurable cred feedback url on the theory that we would
create a separate discourse post to collect feedback for each project in
particular.

We've now realized that no one is using this, so it's just vestigial
complexity now. So I'm removing the logic for configuring the feedback
url on a per-project basis.

Instead, we will always link to a Google form for collecting feedback.

Test plan: `yarn test --full` passes, and I manually checked the links.
