ref. V-AP.01

As a Decidim implementer, I want to know that the Consultations module will not be extended and maintained.

It's important to have a deprecation message in the CHANGELOG for letting the new implementers know that this module will not have support. Also, an alert message for all the administrators so they can know that support for this module will cease in the near future.

Acceptance criteria

• As a Decidim implementer I see in the next release changelog that the Consultations module will be deprecated
• As an administrator when I go to the Consultations admin section I see a callout that says "Consultations module will be deprecated in the near future. We're working on the next cryptographic secure version called Votings."
