[VOTE][LAZY] Move Jakarta Regexp to Attic

This is a vote to move Jakarta Regexp to the Apache Attic, based on
the outcome of the most recent discussion on the topic.

Since Regexp may not have enough PMC members active, this vote will be
held by lazy consensus. If you object, please also provide a
reasonable explanation.

Vote runs for a week, ending no sooner than Mar 28th, ~8:00 pm Eastern
US. Vote is being held on general@jao but is being cross-posted to
ensure we reach the full audience. Please include general@jao on any
replies.
