Implement SMS Templates for Auth

[elleryfamilia]

Currently the SMS that goes out says "Your code is 000000"

Ideally we are able to customize a template and insert the code as a variable:

Nhost - Here is your code: {{verification_code}}. Don't share it with anyone

To push things even further, you could even make Auth variables available for the templates:

{{first_name}}, here is your code: {{verification_code}}. Don't share it with anyone

I think we can have this as an environment variable: AUTH_SMS_TEMPLATE.

I'll move this issue to Hasura Auth for now.

A AUTH_SMS_TEMPLATE may be the quickest way forward, but we would miss translations. Eventually we will likely need to implement the same system as for email templates

Can I pick this up next days? I can implement the template approach.

Yes, definitely!
