fix: remove Jetty dependency management due to unavailable versions

- Jetty 12.0.x versions greater than 12.0.9 do not exist in Maven Central
- Attempted 12.0.10, 12.0.12, 12.0.16 - none are available
- Next available versions are in 12.1.x series
- Remove Jetty dependency management to rely on transitive resolution
- Allows build to proceed with Jetty versions from Spark/Hadoop dependencies
- Can revisit with explicit version pinning if CVE concerns arise
