[feature] Email confirmation email wording when signups need approval

[f0x52]

Is your feature request related to a problem ?

When someone signs up for an instance with approvals turned on, they get an email to confirm their email, but no other info that their account will still be pending, even after confirming the address.

Describe the solution you'd like.

More specific wording that makes it clear that validating the email is the first step, and you'll need to wait for approval afterwards

Describe alternatives you've considered.

know too much about the signup flow beforehand :P
