Use default resolver in MillAlg

... instead of hardcoding Maven Central. If the default resolver is not
overridden it, it will be Maven Central, so nothing will change in this
case.

I'm doing this for the same reason as given in
#1899 where the
hardcoded Maven Central was replaced in `SbtAlg` with the default
resolver.
