### Description
By adding categories, we gained more useful signal on breakage even when
people don't submit descriptions, but by limiting open text to only the
"Something Else" category, we also decreased reports that included any
text (down from about 64% before the change to just under 19% overall
since). Allowing users to add text for any category would be a quick win
to broaden signal a bit.

### Steps to test this PR

- Go to AppTP status page (or silent notification)
- Tap `Help us improve` -> `Submit a report` (or `Having problems with
an app`)
- Select an app
- Notice that you still must select a category, but all categories (not
just "Something else") will now allow text input
