Add Newsletter Signup as a replacement to Register, until even site is ready

[goodtocode]

Goal: Add Newsletter signup as a replacement to Registration HTML widget
Future: Revisit this change, when DataFestAfrica registration opens properly

Tasks:

1. Add Newsletter Signup HTML widget as a replacement to Register
2. Can be a new section, or a replacement for Register
   Pre-Registration-Open
3. Can replace registration section with newsletter
4. OR can redirect Register buttons to new newsletter section
   Post-Registration-Open
5. Registration HTML widget needs to take ownership of registration sections
6. Newsletter can be canceled, or can remain...either way, needs to be it's own section

From leadership...
We can use getrevue for that I think

Then link to the website & twitter.

So who will have the access to the newsletter content The leadership??

[goodtocode]

What happened with the Twitter feed is that they are able to setup an external app registration, and/or copy+paste the integration HTML/JS and send it to us. Then they take over content, while we integrate the HTML/JS block. So yep, leadership manages the content and we manage the integration and the look/feel.

PS. I understand that the 3rd party vendor has changed from getrevue. Awaiting details from the team @Gift-Ojeabulu. Thanks so much for your strong engagement @Divyansh-0 !!
