Issue description

Configuration validation reports:

Configuration error at 'provider.httpApi.authorizers.jwtAuthorizer': unsupported value

Even when the configuration generates a valid CloudFormation template that successfully deploys a AWS::ApiGatewayV2::Authorizer

---

With configValidationMode: error (to be the default in future releases) this is preventing me from deploying an authorizer.
I have tried a number of configurations and attempted to satisfy the authorizerSchema in serverless/lib/plugins/aws/package/compile/events/api-gateway/index.js but nothing seems to work for me.

As an aside, maybe this should be a separate issue, but the docs say to use type: jwt while it seems the correct setting is type: token

Start with the authorizerSchema in serverless/lib/plugins/aws/package/compile/events/api-gateway/index.js and reproduce the reported error using the serverless.yml configuration and serverless package. Compare the validation result with the generated AWS::ApiGatewayV2::Authorizer template and the linked HTTP API documentation; done means the valid configuration passes validation and the documented authorizer settings are consistent.
