Add a section for Body cannot be empty

Ideally it should explain something about the error.

Additional information

I created a file jsoref/choco@f613096

When I browse to it right now:
https://github.com/jsoref/choco/blob/develop/.github/ISSUE_TEMPLATE/ReportPackageIssue.yaml

I see:

There is a problem with this template

Body cannot be empty. Learn more.

Fwiw, I tried to model the file after https://raw.githubusercontent.com/github/docs/main/.github/ISSUE_TEMPLATE/improve-existing-docs.yaml

Fwiw, there's also

@jsoref Did you mean to have this link for "What article on docs.github.com is affected?" question?

[jsoref]

Sigh. Thanks. Clipboard fail trying to do three interrelated things at once.

@jsoref
Thanks so much for opening an issue! I'll triage this for the team to review 👀

👋 @jsoref Thank you for your patience on this one. 💛

I’ve spoken with the team, we were able to reproduce this instance without the Body cannot be empty error populating. However, we did so without the --- around the name and description, as the body tag is found externally here.

As for adding the error, you or anyone else are welcome to open a PR adding the error with a sentence similar to “The template body key:value pair must not be empty.” And for more info include a link to the “Syntax for issue forms” article

[jsoref]

I probably should have explained that in my case, I'm pretty sure the reason for the error was the ---. I'm not sure which will be more common: not having a body or for some reason copying a --- and thus causing it not to be seen.
