Ability to add BCC email(s) to authentication emails sent by Supabase

[Ninjeneer]

To keep a track on what's happening on a platform, it is very useful to see the mails that are sent by Supabase. We can already do it if you provide a "regular" SMTP account such as Gmail, where sent mails appear in the Sent inbox.
However, when using AWS SES for example, the whole process becomes very blur and we don't know anymore what's happening. Receiving a copy of those emails on a regular email address would help a lot

Adding an extra field in the email setup to define one or more BCC emails
