[bug#43765] [PATCH] gnu: Add go-github-com-errata-ai-vale.

[Gabriel Arazas]

One of my favorite writing tools and also my first dive into Go thru
packaging this program.
I do have a couple of questions/feedback regarding packaging Go packages:

* When do I add the missing dependencies? Is it required or just a
preference? Are indirect dependencies included to be listed?
I noticed that some of the Go packages have incomplete
depedencies on the package definition and you can still build the
Go packages even if you remove it (or at least my package does that).

* I feel like there's a missing section in the documentation
regarding naming Go packages since I noticed there are some
inconsistencies. For example, there are packages that starts with 
'go-github.com'
and 'go-github-com'. (To be fair, I only found like 2 packages that has
different naming so far.)
