[Schema Inaccuracy] issue/pr response fields marked as required nullable unnecessarily (?)

Schema Inaccuracy

The assignees (issue and PR) and requested_reviewers and requested_teams (PRs) are required nullable arrays.

Experimentally it doesn't look like these are ever null in responses, nor is there any reason for them to be as an empty array should play that role just fine.

👋 @xmo-odoo from github/issues:

I couldn't find anywhere in the docs that those fields are nullable. According to the GitHub API documentation, these fields are indeed arrays, but they are not documented as nullable. Can you please point to the problematic doc where it mentions its a nullable field?

@hasan-dot here is the schema for assignees in Issues:

"assignees": {
  "type": [
    "array",
    "null"
  ],

The Pull Requests are identical, and the requested_* fields are similar:

"requested_reviewers": {
  "type": [
    "array",
    "null"
  ],
[...]
"requested_teams": {
  "type": [
    "array",
    "null"
  ],
