Bump exec-maven-plugin target to 3.5.0 and fix PLUGIN_UPGRADES inconsistencies (#12200)

- exec-maven-plugin: bump from 3.2.0 to 3.5.0 (3.1.0 and earlier use
  MavenSession.getContainer() which returns null in Maven 4)
- Fix PLUGIN_UPGRADES list: exec-maven-plugin had wrong groupId
  (org.apache.maven.plugins) and artifactId (maven-exec-plugin)
- Fix compiler-plugin min version in PLUGIN_UPGRADES: 3.2.0 → 3.2
  (3.2.0 does not exist on Maven Central)
