Possible to configure a webhook via an attribute:

`
#[ApiResource(operations: [

new Post(openapi: new Webhook(name: 'a cute name')
)),
new Get(openapi: new Webhook(
    name: 'a cute name',
    pathItem: new PathItem(
        get: new Operation(
            summary: 'Something else here',
            description: 'Something else here for example',
        ),
    )
)),

]
)]`
and generate documentation

I will update: just $path should be enough

Nice! Do you think we could add a functional test to features/openapi/docs.feature with a webhook?
