Research direction

Start at #/components/schemas/pull-request and inspect the definitions of head.label and head.user, using the reported curl response for pull request 51976 as the failing example. Mark both properties nullable and document the nullability conditions, while preserving the existing handling for head.repo; verify the generated schema reflects these changes.

Description

feature

Schema Inaccuracy
The current schema for #/components/schemas/pull-request defines head.label and head.user as required.

Expected
head.label and head.user should have nullable: true with the nullability conditions documented (from what I understand, if the user's account was deleted for some reason: all the cases I can see are for "ghost" users)

Reproduction Steps
❯ curl -s https://api.github.com/repos/odoo/odoo/pulls/51976 | jq .head
{
"label": null,
"ref": "12.0",
"sha": "3cf7aba2e293417c6e8a6a4785624c8315ccbb7a",
"user": null,
"repo": null
}
Side-note
The same issue was fixed for head.repo as reported in https://github.com/github/rest-api-description/issues/161 and https://github.com/github/rest-api-description/issues/424, would be nice to also add a description to that property explaining the conditions under which it can be null.
