Description

The "requestBody" in generated api is always optional so I cannot access to requestBody members:

Reproduction

1. Generate api
2. Try to get access to any requestBody's member

Expected result

All requestBodies are NOT optional

Required

• My OpenAPI schema is valid and passes the Redocly validator (npx @redocly/cli@latest lint)

Extra

• I’m willing to open a PR (see CONTRIBUTING.md)
