types.ts: [BUG]: the type `ExtractRequestBody` returns `never`

What happened?

While updating @octoit/plugin-rest-endpoint-methods to use the latest release of this package, in https://github.com/octokit/plugin-rest-endpoint-methods.js/pull/632, the tests are erroring out.

I managed to narrow it down to the ExtractRequestBody type, as can be seen in the code snippet below

https://github.com/octokit/types.ts/blob/e7956808d0e1d019c3f6bc7a96d29468dc16ff42/src/generated/Endpoints.ts#L21-L37

Versions

@octokit/types v9.1.2 typescript v5.0.4

Relevant log output

The following error is for the PATCH /repos/{owner}/{repo}/labels/{name} endpoint. Every error is similar to it
