Patch Release for Netty Vuln

[ZachChuba]

Hi,

My organization has a very low risk tolerance policy, and currently there is no pulsar version available that addresses the most recent netty high severity vulnerability GHSA-4g8c-wm8x-jfhw. Netty version is already upgraded in master, but we're waiting for a 4.0.3 release with the patch included. Unfortunately, my organization cares more about existence of a vulnerability than the likelihood and impact of exploitability.

Thanks.

@ZachChuba The releases that include Netty 4.1.118 with the fix for CVE-2025-24970 are currently in the release voting stage. Please participate in validating the release candidate versions. This is also a valuable way to contribute to the Apache Pulsar OSS project.
