fix(java-runtime): dependency ranges make Maven download too many files (#5005)

Given a dependency version range, Maven will download metadata for all
possible versions before every (uncached) build. This takes a long time,
before finally resolving to the latest version anyway.

Instead, we use the Maven 'versions' plugin to resolve our wide ranges
to point versions. We want the "latest matching" version anyway, and if
we don't the resolution now (which downloads the .poms of all possible
versions) it will happen during every single build.
