fix(ci): latest tag docker does not move to newest version

When you created a new version of Slyde then the `latest` tag did not move to
that new version. The major and minor tags do move. So for example if you
pushed `v1.2.3` then `1`, `1.2`, and `1.2.3` do get created/moved, but the
`latest` tag does not, it does now.
