### What changes were proposed in this pull request?

This PR aims to update `doap_orc.rdf` file.

### Why are the changes needed?

The following Apache Projects page is populated from `doap_orc.rdf`. We need to keep it up-to-date. For example, we need to show `1.6.9 (2021-07-02): Apache ORC 1.6.9` instead `1.4.3 (2018-02-09): Apache ORC 1.4.3`.
