Add magiclink Provider under Users & Permissions

[rikonor]

What does it do?

This change adds a magiclink provider under the Users & Permissions plugin.

Why is it needed?

This allows Strapi to support authenticating a user coming in via a "Magic Link". The need for this change came about when I was using NextAuth and their email provider (See NextAuth/email) which sends the user a magic link.

I initially stumbled upon NextAuth through this tutorial (See Strapi Blog: User Authentication in NextJS with Strapi). It covers authenticating with social providers but not with the stock "magic-link" method, which necessitated this change.

How to test it?

To test this change, start Strapi as usual, and under Settings > Users & Permissions > Providers, click on Magiclink, enable it and specify a Client ID which is equivalent to a key.

Then to authenticate (and possibly register) a user, make a call to /api/auth/magiclink/callback?email=<email>&access_token=<key>.
