Mistake in the instructions for setting up SMTP

Summary

Comment in dogmap/init.py on line 77 states that the environment variable for GMAIL_SMTP_HOST is smtp.google.com, but it should actually be smtp.gmail.com.

Steps to reproduce

Place GMAIL_SMTP_HOST="smtp.google.com" in .env

What is the current bug behavior?

Using the incorrect host causes a timeout and a connection error when the server tries to send an email.

What is the expected correct behavior?

Email is sent.

Possible fixes

Simply change the instruction from using smtp.google.com to smtp.gmail.com instead to prevent others from encountering the same error.
