Remove/Stop offering D6 releases on https://civicrm.org/download
We're still publishing, whether through an error or through an oversight, Drupal 6 releases despite no longer supporting D6 and publishing a D6 tarball that doesn't work on D6 (No PHP 3.x support in CiviCRM).
Can we remove this source of confusion.
