vendor test dependencies instead of installing via network

We can vendor the test dependencies such as go-md2man, git-validation
and goimports. This allows us to always install the same version as
specified in go.mod. Also we do not rely on a network connection for
this.

The advantage with this method is that dependabot will also update the
dependencies for us and we do not have to hardcode versions in the
Makefile.
