annoucements page on website

Hi all,

We've added a new announcements page to the Raku documentation website.

As soon as the changes propage through the tool chain - probably after 
about 10.30am UTC - whenever you open the website after a new 
announcement has been made that you have not read, you will get a popup 
of the announcement.

Once cancelled, that message should not normally appear again.

You will only see a new announcement when one is added to the top of the 
announcements page.

All announcements can be seen by looking at the new announcement page 
(link can be found in Introduction/Beginning)

You can suppress all announcement popups using a toggle that can be 
found in the navigation's More dropdown.
