Create vercel.com template

[RhysSullivan]

Description

Hey, we're setting up domain connect to make it easier for our users to add domains

When a user is configuring a domain on Vercel, there's 3 fields they need to set:

1. TXT Verification - The user may need to do this to prove ownership of their domain, optional
2. CNAME Record - Only used if the user is adding a subdomain
3. A Record - Only used if the user is adding an apex domain

Here's an example of the types of states the domain config can be in:

I'm also working on getting us setup as a DNS Provider with Domain Connect support as well

Thanks for taking a look at the PR, let me know any fixes that need to be made

Three commits could be squashed to single one, but that's a minor nit. The template data itself looks good to me.
