[Schema Inaccuracy] has_discussions field marked as mandatory but not returned in responses

Schema Inaccuracy

disclaimer: I am neither an openapi nor an openapi-generator expert, and I'm interacting with github enterprise instance at my company, not 100% sure if the issue I'm facing really is a spec inaccuracy, but I thought this would be a good first step to ask before deciding to file the issue somewhere else)

An openapi-generator client generated from from https://github.com/github/rest-api-description/tree/main/descriptions/ghes-3.6 used to retrieve a pull_request fails on parsing the response "repo" field as it cannot find "has_discussions" inside (which is marked as required in the spec). The field is not found in the response obtained via curl leading me to believe this could be a schema inaccuracy

Expected

"repo" returned by pulls GET call should include has_discussions field, but does not.

Reproduction Steps

reproduction with curl

apologies for not showing the entire answer, but I hope this excerpt is enough

curl https://git-enterprise-host/.../org/repo/pulls/12345 -H "Authorization: token $GHE_TOKEN"  -H "Accept: application/vnd.github+json" 2>/dev/null  | grep -i has_
      "has_issues": true,
      "has_projects": true,
      "has_downloads": true,
      "has_wiki": true,
      "has_pages": false,
      "has_issues": true,
      "has_projects": true,
      "has_downloads": true,
      "has_wiki": true,
      "has_pages": false,

the schema at https://raw.githubusercontent.com/github/rest-api-description/main/descriptions/ghes-3.6/ghes-3.6.json describes has_discussions field as required in the response, but it's missing

If one were to reproduce with an openapi-generator python client created as described in #2274 parsing the response would fail with:

E           ....exceptions.ApiTypeError: repo is missing 1 required argument: ['has_discussions']
