Remove Go 1.13 support
Go 1.13 has reached EOL. Looking at https://gitlab.com/gitlab-org/build/CNG/-/blob/master/ci_files/variables.yml (13-8-stable
, 13-7-stable
, and 13-6-stable
branches), we can see that GO_VERSION
is 1.14 for the last three minor releases. As a plus, we'll finally be able to use T.Cleanup
.
