Disable gradle 7 module metadata publication (#162)

## Summary

This previous PR #160 addresses the runtime dependencies for fat jar.
The runtime dependencies are present in pom file, but not in ELRed ivy
file. Instead they are present in gradle module metadata file. It seems
ELR process is considering gradle module metadata file once they are
published hence dependencies are not present is the ivy file. So
disabling gradle module metadata publish.
