Open Pull Request Rest API showing undefined at issue field

[MateusAndrade]

What article on docs.github.com is affected?

• Currently, the docs regarding opening a PR using the Rest API shows an undefined for the issue field.

• Opening Pull Requests: https://proxy-ga.blitzz.co/proxy/123456/docs.github.com/en/rest/reference/pulls#create-a-pull-request

What part(s) of the article would you like to see updated?

It would be great to have a description of this field, showing how we can link this PR with an issue that already have been created. Maybe something like this:

<p>Issue linked to the pull request. See \"<a href=\"https://proxy-ga.blitzz.co/proxy/123456/docs.github.com/github/managing-your-work-on-github/linking-a-pull-request-to-an-issue\">Linking Issues with Pull Requests</a>\" in the GitHub Help documentation to learn more.</p>

Which will be rendered as:
