circleci: Remove auto deploy to PyPI

We're using 2FA to upload PyPI packages. Since there is no support for
2FA for headless accounts yet, we will be uploading manually. Hence we
disable the Release workflow in CircleCI and remove any associated
auto-deploy commands. Doing this all in one commit to make it easier
to revert this change in the future should PyPI support 2FA for
headless accounts.
