Update GoodCollective Homepage to include stats & explainer

[decentralauren]

Business Description

Current GoodCollective home page dumps people into a list of Collectives without any context for where they are or what to do! This update will add a section at the top of the page that describes GoodCollective and offers some quick stats.

Detailed Description of Functionality

Users will see this page when they navigate to gooddollar.org/goodcollective or goodcollective.xyz, whether or not they have a connected wallet. The new page contains:

• Header copy
• A short description
• A "How it works" button that links to a sub-page
• A "Donate to a Collective" button which indexes to the Collectives part of the same page (scrolls down)
• A "Create a Collective" button which directs users to our typeform
• Impact Stats, which include: Total # of pools/ Collectives, Total amount of donations (all time), Total # of wallets paid through collectives
• Another header and short description
• A list of all collectives as cards (which link to collective detail pages)
