Email -> Magic Link Login 🔗

As noted by @ndrean in https://github.com/dwyl/learn-postgresql/issues/84#issuecomment-1277916838 💬
We don't currently have the concept of Magic Links in this project. 🪄
My reasoning was that we don't _want_ people clicking links in email because it promotes [**`Phising`**](https://en.wikipedia.org/wiki/Phishing) ... 🙄
But we ***`do`*** already have email verification.
e.g: [templates/verify.txt#L6-L7](https://github.com/dwyl/aws-ses-lambda/blob/33f1796ec2df36095a21784056638e80b6a2ca5b/templates/verify.txt#L6-L7)

# Todo

+ [ ] Gage the demand from other people in the community for this feature before adding it. Might be that we only consider it as part of the re-build with `gen.auth` #133 -> #207

P.S: Just tried the [`email`](https://github.com/dwyl/email) send function and it still all works. 🤯

I probably shouldn't be surprised because nothing has changed and it worked fine last time I checked ... ⏳ 💭 😜
