Bumps openapi-backend from 5.21.3 to 5.22.0.

Release notes

Sourced from openapi-backend's releases.

5.22.0

Response header validation now honors the OpenAPI required property, which may change which responses pass validation.

Changed

• Response header validation now honors required. Optional headers may be absent in superset and exact matching, but any optional header that is present is still checked against its schema. A header declared required: true is checked even without a schema. If your definitions relied on every declared header being treated as required, mark those headers required: true (#1034, thanks @​wangyusheng1985)

Dependencies

• Lockfile and development dependency updates.
