Add Github authentication

[skks1212]

Add github authentication for the following :

• 1. let users update their details through the app rather than sending a PR
• 2. let users receive push notifications about what rank they stand.
• 3. Have badges that a user receives on completion of specific tasks or goals
• 4. you can think of more features

It's a nice idea, but we are not going to get a backend so... : (

Can't nextjs itself handle it?
How about this?
We'll make an API endpoint in nextjs that'll dispatch an email with sendgrid or anything.
And invoke that endpoint every week by a github workflow? 😎

Or can github workflow itself do it alone? 🤔

[skks1212]

sounds good, can you make it run from a dummy email for now? Il help

@rithviknishad As this NextJS project only uses SSG. The choice is only to go for GH workflow
