bpo-43888: Remove coverage builds from CI by ammaraskar · Pull Request #25679 · python/cpython
We introduced code coverage a while ago as part of https://bugs.python.org/issue23721 and python/core-workflow#2 but it looks like this feature isn't really utilized by many people based on searching for "codecov" on github and bpo. These builds take way longer due to the instrumentation and this is cutting into valuable CI time. The builds are now also failing on master with the new timeout mechanism.
Let's just get rid of the coverage builds and see if anyone complains :)
