Update protobuf-java dependency in graphql-java-support/pom.xml to the latest version

[sefi18]

The currently used version of protobuf-java is 3.9, which has a reported CVE issue:

https://cloud.google.com/support/bulletins#gcp-2022-001
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22569

Even if this has no attack vectors here it cause alerts in scanning tools like Whitesource.

Expectation:
Please update to the latest version (version 3.19.3 at the time of writing).
