Loose version selection rules for Alpine packages

A recent update of Alpine package repositories broke the actions based on the
alpine image.

Today I've learned that Alpine don't keep older versions around. To avoid it
breaking again, I'm using the `~=` matcher instead of the strict `=` version
selector.

Using `~=` is valid for `hadolint` as well.

Closes #2
