# Update google translation lib

- Update google translation lib to use the latest version of the google-translate-api library.
- Use the google service account file to authenticate with the google translation API.
- `.auto-translate-config.json` file is updated to include the `googleServiceAccountKey` field.
- this field is used to store the path to the google service account file.

## Config file

`.auto-translate-config.json` with the `googleServiceAccountKey` field:

```json
{
    "automaticTranslation": true,
    "translatorProvider": "google",
    "azureTranslateKey": "the-azure-key",
    "googleTranslateKey": "the-google-key",
    "googleServiceAccountFile": "/home/vrba/.auto-translate/translations-xxxx-aaaa.json"
}
```

`translations-xxxx-aaaa.json` looks like this:
```json
{
    "type": "service_account",
    "project_id": "translations-xxxxx",
    "private_key_id": "<private-key>",
    "private_key": "<private-key-content>",
    "client_email": "applipress-translate@translations-ssss.iam.gserviceaccount.com",
    "client_id": "<client-id>>",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://oauth2.googleapis.com/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/applipress-translate%40translations-xxxxx.iam.gserviceaccount.com",
    "universe_domain": "googleapis.com"
  }
  
```
