Merge #619

619: Update getting_started code-samples r=alallema a=meili-bot

_This PR is auto-generated._
Update the code-samples.meilisearch.yml according to the [documentation issue](meilisearch/documentation#2499). 
The `api_key` field is missing in the instantiation of the client in the getting started samples.
Add `aSampleMasterKey` as the `api_key`.
cURL example:
```bash
    curl \
  -X POST 'http://localhost:7700/indexes/movies/documents?primaryKey=id' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer aSampleMasterKey' \
  --data-binary `@movies.json`
````
