[UI] Add community component

[amirhouieh]

There are two new additional components need to be build and added to the interface. Where they need to be used have not been confirm but the look is going to be same as it is on figma https://www.figma.com/file/YPw6IQMkg7aybAZWxjrkrB/UI-%E2%80%93-V1?type=design&node-id=2815-17761&mode=design&t=wlue9pfgo6AwNA3P-4

• Subscription form
• Join Discord card

The email subscription functionality was done in:

#211

And the join discord component was done in:

#209

I closed the PR with the old email subscription UI - #210

Shall I reopen it? Or do we just keep the new email subscription UI?
