build(deps): maven-gpg-plugin 3.2.7 in the generator

Let's use the latest maven-gpg-plugin in the generator. It seems that there's a concurrency problem in the old versions.

b/421886950

This version matches what we have in https://github.com/googleapis/java-shared-config/blob/main/native-image-shared-config/pom.xml#L190C17-L200C32.

I'll create another CL that modify the generated pom.xml files.
