ci: Fix artifact upload logic

Curl doesn't exit with non-zero code on bad HTTP responses unless you
include the `--fail-with-body` option. This should allow our retry logic
to actually work.

This also changed from `-v` which is too verbose to options that will
print response headers and the HTTP status code. A new failure example
will look like:
```
h /tmp/tmp.sh
