Deprecate Mailchimp for Substack

[rihp]

The landingpage is currently using a mailchimp email sign up, so when we are going to post something on substack, we should export all the subscribers from mailchimp and import them into substack.

this process takes about 10 to 15 minutes, and has to be done each time

The other alternative to stop doing this manually is:

• changing the sign up component in our landingpage to integrate directly with substack #14
• Before we deprecate mailchimp entirely, make sure to migrate all subscribers to substack

I looked into this, and there is a possibility to use this codegen tool to create a styled sign up section like this one

our substack domain is
blog.polywrap.io

This is the Landing Page repo, and the line on which the component is implemented:

https://github.com/polywrap/landing-page/blob/master/src/components/Footer.tsx#L209

And this is the component on which Mailchimp is currently set up on, and which we need to update to connect to substack

I have opened a PR to replace the signup form with the Substack embed:
https://github.com/polywrap/landing-page/pull/142

Important note: With the Substack embed, we are losing our old GA event:

ReactGA.event({
        category: `Button-${location}`,
        action: CTA,
        label: "Early Access",
      });

CTA here was "Join our Discord", so I figured this was an old event in any case, and decided to go forward with what's potentially a heavy-handed change.

I have also tried out an alternative approach where we can manually call substackapi's endpoint using our old form/signup button, if we want to do that.

Just let me know. 😄

@rihp one more important note:
For future reference - the correct subdomain for Polywrap is the customized one (blog.polywrap.io), as using polywrap.substack.com threw all kinds of weird errors.

Had a quick call with pileks, and we were able to get this one wrapped!! Thanks a lot @pileks 🔥
