HDDS-4870. Bump jetty version

[elek]

JIRA: https://issues.apache.org/jira/browse/HDDS-4870

What changes were proposed in this pull request?

org.eclipse.jetty:jetty-server is a lightweight highly scalable java based web server and servlet engine.

Affected versions of this package are vulnerable to HTTP Request Smuggling. If GZIP request body inflation is enabled and requests from different clients are multiplexed onto a single connection, and if an attacker can send a request with a body that is received entirely but not consumed by the application, then a subsequent request on the same connection will see that body prepended to its body. The attacker will not see any data but may inject data into the body of the subsequent request.

See: https://app.snyk.io/org/elek/project/73e69ab2-cc42-47f1-965b-2a8ba3daaeb6/
