[PATCH] Documentation/MyFirstContribution: add setup template for git send-email

[Vivan Garg <gvivan6@gmail.com>]

The doumentation under [[setup-git-send-email]] fails to describe what
needs to be done with the SMTP server information. Although the email
provider will tell you the specifics (such as the serverport), it must
always be added to gitconfig. By adding this, a new contributor can
simply find the information and insert it into the template, saving them
the headache of figuring out what to do with the information.
Therefore, add a template that describes what to do with the
information obtained through the email provider.

The commit subject line is over 50 columns long, but the file path takes 
up the majority of the space, which I thought was important because it 
shows that only the documentation is being edited. 

The reason I felt compelled to include this is that, while it is simple 
to find the SMTP server information required from the email provider, it 
takes a little extra effort to figure out what to do with that information.
However, because it must always be added to git config, making this change 
makes it easier for anyone to find which fields they need and what they 
need to do with the information.
