Hard coded sub page description for Important Announcements Page

Summarize

Please, describe what the PR does, the changes you have made.

I have added new block in base.html and overrided it in announcement.html.

Also, mention the key points if any to look into while code reviews

The description I could find for this page is "Important Announcements regarding Kerala Rescue Operations".

Please suggest something better if somebody has a better suggestion.

@jinojossy93 Can ya modify this to include per announcement description please ? #1054 has been merged which gives a permalink for each announcement. It would be great if title & description of each announcement page is unique so that the link previews in whatsapp/social media stands out.

Also try to change <meta name="Description"> too

[jinojossy93]

@subins2000 lemme check the latest changes.
I'll start work on that soon.

@subins2000
Completed the requested changes. Please have a look

Tested this. It works good. By having descriptions, the link preview in whatsapp/social media for individual announcements will be better.
