update developers list in pom.xml

[jodygarnett]

This is a follow up to #4700 updating the pom.xml structure.

The original is:

  <!-- TODO developer part-->
  <developers>
    <developer>
      <name/>
      <id/>
      <organization/>
      <organizationUrl/>
      <email/>
      <roles>
        <role/>
      </roles>
      <timezone/>
    </developer>
  </developers>

The following is removed from #4700 above:
