Docs: Lambda deployment docs: `requestContext`
### Issue Description

Today, I was following [this documentation](https://www.apollographql.com/docs/apollo-server/deployment/lambda/#running-locally). 

I kept encountering the following error when running
`serverless invoke local -f graphql -p query.json`

`query.json` before
```
{
  "version": "1",
  "httpMethod": "POST",
  "path": "/",
  "headers": {
    "content-type": "application/json"
  },
  "requestContext": {}, # This is the problematic line
  "rawQueryString": "",
  "body": "{\"operationName\": null, \"variables\": null, \"query\": \"{ hello }\"}"
}
```

`query.json` fixed
```
{
  "version": "1",
  "httpMethod": "POST",
  "path": "/",
  "headers": {
    "content-type": "application/json"
  },
  "requestContext": { "http": { "method": "POST" } }, # Adding these fields seems to resolve the issue.
  "rawQueryString": "",
  "body": "{\"operationName\": null, \"variables\": null, \"query\": \"{ hello }\"}"
}
```

In the recent update of `"@as-integrations/aws-lambda": "^2.0.0",`, I noticed [this line](https://github.com/apollo-server-integrations/apollo-server-integration-aws-lambda/blob/main/src/request-handlers/APIGatewayProxyEventV2RequestHandler.ts#L14), where there is an expected field, `http.method`
