enable -Werror on CI
Regular compilation with -Werror
is an unnecessary burden, but verifying code with it on CI seems reasonable.
Because the release of TOX 4.0 yesterday broke our CI (not finding the mako
), I added a commit for downgrading and also updated ci-templates
and the Debian image.
Added an extra commit removing an unused variable that was recently merged.
