Link multiple accounts with the same email

[kc-hsh-value]

Allow users to log in with a provider of their choice.
Then once they are authenticated, they will be able to link accounts from different providers
These accounts will be used for his potential authentication in the future

Example (1 table for users (the one used for authentication) and 1 with user info)
-log in with discord with email a@a.a
-as soon as i am logged in I link my facebook with email b@b.b
-i set my image url inside the userinfo table with my user id.
-i log out

then
-i log in with facebook
-the authentication should redirect to the same account as before

plus:
i suggest adding instagram authentication
