[messaging-dev] Update ee4j.messaging/contact to point to new mailing li

[Piotr Żygieło <piotr.zygielo@xxxxxxxxx>]

Hello Messaging Committers

While after renaming
  https://projects.eclipse.org/projects/ee4j.jms
redirects to
  https://projects.eclipse.org/projects/ee4j.messaging
there is one thing that I find that could be updated.

Please consider to edit
  https://projects.eclipse.org/projects/ee4j.messaging/contact
which:
- currently points to archived (not subscribable)
https://accounts.eclipse.org/mailing-list/jms-dev (that is fine), but
- is silent about new https://accounts.eclipse.org/mailing-list/messaging-dev

https://accounts.eclipse.org/mailing-list/jms-dev mentions the
replacement list, but perhaps it could be listed directly on the
project page?
