JerseyEventSink#send throwing non IOExceptions

[jbescos]

Relates to jakartaee/rest#1196

Maybe we should catch Throwable instead of Exception.

I don't know what was the reason to catch only IOExceptions, but in the case of Helidon a runtime exception is thrown:
java.io.UncheckedIOException: java.net.SocketException: Broken pipe

Anyway, as it returns a CompletionStage I think we should not throw exceptions in JerseyEventSink#send.

Also UncheckedIOException is caught in ChunkedOutput

This needs to backported to 2.x, too
