Empty stage in API Gateway output for endpoints

Nadie ha tomado este issue todavía.

With this `serverless.yml`:

```
service: scraperator
frameworkVersion: "3"
provider:
name: aws
runtime: python3.9
stage: local
region: us-east-1
logs:
httpApi: true
deploymentBucket:
name: serverless-deploys
serverSideEncryption: AES256
httpApi:
cors: true
disableDefaultEndpoint: false
plugins:
- serverless-python-requirements
- serverless-localstack
custom:
stage: ${opt:stage, self:provider.stage}
localstack:
stages:
- local
autostart: false
functions:
config:
handler: capture.config
events:
- httpApi:
method: GET
path: /config
capture:
handler: capture.handler
events:
- httpApi:
method: POST
path: /capture
```

A successful deploy yields this output:

```
endpoints:
GET - https://746fbc6e.execute-api.localhost.localstack.cloud:4566//config
POST - https://746fbc6e.execute-api.localhost.localstack.cloud:4566//capture
```

Note the `//` where there should be `/local/`.
The URL as printed does not work. However, removing a `/` (e.g. https://746fbc6e.execute-api.localhost.localstack.cloud:4566/config) does work.

Reproduzca el despliegue utilizando el serverless.yml proporcionado y compare las URL de los endpoints impresas con las URL funcionales descritas en el issue. Siga cómo el plugin de Serverless formatea las rutas de los endpoints de API Gateway y, a continuación, verifique que los endpoints desplegados incluyan el stage local configurado y contengan una sola barra antes de la ruta.
