feat: OpenAPI 3.1 support (#8367)

- New top-level field - `webhooks`. This allows describing out-of-band webhooks that are available as part of the API.

- New top-level field - `jsonSchemaDialect`. This allows defining of a default `$schema` value for Schema Objects

- The Info Object has a new `summary` field.

- The License Object now has a new `identifier` field for SPDX licenses. This `identifier` field is mutually exclusive with the `url` field. Either can be used in OpenAPI 3.1 definitions.

- Components Object now has a new entry `pathItems`, to allow for reusable Path Item Objects to be defined within a valid OpenAPI document.

- `License` and `Contact` components are now exported and available via `getComponent`

- New version predicates and selectors for `isOpenAPI30` and `isOpenAPI31`. This avoids needing to change the usage of `isOAS3` selector.

- New OAS3 components: `Webhooks`

- New OAS3 wrapped components: `Info`, `License`
