[Feature Request] Creating a list of shared-api-keys for the community

### Type of feature request

Other

### Description of the feature you're suggesting

I am proposing that we should add a section in the document, or link a new page for [shared-api-keys](https://docs.discord.red/en/stable/framework_apikeys.html#shared-api-keys)
As it is crucial for cog creators to use the same key values for shared-api, making a list of existing key and api structures to prevent small differences in api namings

For example it could be something like:

# List of existing shared api keys

### Twitch API
https://dev.twitch.tv/docs/api/
API from twitch used to certifying twitch dev applications

**key**
> "twitch"

**parameters**
> "client_id" : client id from twitch
> "client_secret" : client secret from twitch

### YouTube API

### Anything else?
