Describe the bug

The queries to Conan Center via Github API fail to obtain any versions (Failed to look up dependency fmt etc.)

In the attached trace fragment, you can see there are two conflicting Accept headers. Depending on which one is sent first, either raw or json content is returned. If it's json, then parsing fails (without any error message) and no versions are found.

This patch fixes it:
