fix: Resolve .localhost domains on macOS

  By default, macOS does not resolve domains on the `.localhost` tld.

  However we do use this tld for our tests so we need to add `dnsmasq`
  and resolve these domains on the CI or some tests will fail.

  We don't really know why some of them were passing before though.
