[Feature] Add feedback button on the homepage

[magicoder10]

What is the problem? Currently, users send feedbacks by emailing Harry directly. It's hard to track those bug and feature requests this way. There is also no visibility inside the team to directly act on users feedbacks.

Your solution Add a feedback button on the page. The team will be notified through Slack when feedbacks are received from users.
