[Schema Inaccuracy] Missing examples for webhooks

[wolfy1339]

Schema Inaccuracy

The schema doesn't include examples for all webhook event and their actions.
Since the GitHub docs moved to defining the Webhooks from the OpenAPI spec, we have lost the examples that were given.

See also github/docs#22726 which was opened for restoring the examples in the github docs, however it has gone unanswered for over 2 years, and no visible progress has been made on either repo.

Expected

For there to be one example per webhook event per action
