Trying to download large email (>20MB) does not return from the call (no error, no timeout) when options http2: true

#### Environment details

- OS: Linux / Macos
- Node.js version: v18.10.0
- npm version: 8.19.2
- `googleapis` version: 105/109.0.1

#### Steps to reproduce

1. Get a large email from Google API with the options `{http2: false}`
2. The application is stuck: The function call never returns, there is no error or timeout.

Whole request:
```
gmail.users.messages.get({
format: 'raw',
id,
userId: 'me',
},
{http2: true})
```
Notes:

Making the same request using the [Try this API](https://developers.google.com/gmail/api/reference/rest/v1/users.messages/get?apix_params=%7B%22userId%22%3A%22me%22%2C%22id%22%3A%2217d1d453987522ef%22%2C%22format%22%3A%22raw%22%7D#http-request)

Making the same request with the `{http2: false}` option works as well, but since the batch request is not part of the library anymore, it would make the inbox synchronisation too slow.
