[REQUEST] Restrict Access to Members of a GitHub Organization

[etagwerker]

Before we start...:

• I checked the documentation and didn't find this feature
• I checked to make sure that this feature has not already been requested

Branch/Commit:

main branch.

Describe the feature:

As a user
I want to sign in to the system
So that I can see leaderboards regarding our Noko account

Mockups:

It could work similarly to dash where we already have GitHub sign in enabled:

Only after confirming that the person belongs to the right GitHub organization, it will show the leaderboards section:

Resources:

• https://github.com/fastruby/dash already implements this feature.

I will abide by the code of conduct
