e2e test - publisher test screenshot addition for skips (#8114)

### QA Notes
This PR adds the ability to attach a screenshot to the report if dogfood
is down. Upon failing to get a desired response from the API (_e.g.,_
due to it being down), it takes a screenshot like the one below. If API
is down, such screenshot will have message `502 Bad Request` or similar
_(i.e.,_ page will not load properly).

**Overall, this addition to the test ensures that, when test fails, we
know the root cause without having to assume that it was because dogfood
was down.**
