Remove Netty versions metadata from shaded jar

[nanne-rl]

What changed?

• Exclude META-INF/io.netty.versions.properties from the temporal-shaded jar.

Why?

grpc-netty-shaded contributes Netty's versions metadata to temporal-shaded. Consumers that scan classpaths for Netty version mismatches can treat temporal-shaded as another Netty distribution and emit inconsistent version warnings, even though the classes are relocated.

Breaking changes?

No.

Server PR

None.

Testing

• JAVA_HOME=/nix/store/bp2gjhd8vfyv2hg0i90sba2wp47vvflg-zulu-ca-jdk-21.0.11 PATH=/nix/store/bp2gjhd8vfyv2hg0i90sba2wp47vvflg-zulu-ca-jdk-21.0.11/bin:/Users/nanne/.nix-profile/bin:/usr/bin:/bin:/usr/sbin:/sbin ./gradlew --gradle-user-home .gradle --offline :temporal-shaded:shadowJar
• Verified temporal-shaded/build/libs/temporal-shaded-unknown.jar does not contain META-INF/io.netty.versions.properties.
• Verified the shaded jar manifest still contains Multi-Release: true.
