MINOR: Revert Jetty to 9.4.25 (#8183)
MINOR: Revert Jetty to 9.4.25 (#8183)

9.4.25 renamed closeOutput to completeOutput
(https://github.com/eclipse/jetty.project/commit/c5acf965067478784b54e2d241ec58fdb0b2c9fe),
which is a method used by recent Jersey versions including the
latest (2.30.1). An example of the error:

> java.lang.NoSuchMethodError: org.eclipse.jetty.server.Response.closeOutput()V
> 	at org.glassfish.jersey.jetty.JettyHttpContainer$ResponseWriter.commit(JettyHttpContainer.java:326)

The request still completes and hence why no test fails. We should think about how
to improve the testing for this kind of problem, but I want to get the fix in before
2.5 RC0.

Credit to @rigelbm for finding this.
