Fix Windows issue in ZipkinResolver
Fix Windows issue in ZipkinResolver

Problem:
The current resolver setup configured
a resolver URL that wasn't valid on Windows, leading
to build failures.

Solution:
Replace the resolver with one that is
cross-platform, using Java's APIs that are supposed
to work across platforms.
