The tests GitHub workflow is not working

Tests runs fine on my machine. Seems like to fix it here this needs to be added to the end of the `composer.json` file:
```json
"config": {
"allow-plugins": {
"thecodingmachine/discovery": true
}
}
```
and add `--ignore-platform-req=composer-plugin-api` to [tests.yml](https://github.com/botman/driver-telegram/blob/master/.github/workflows/tests.yml) `composer install` section.
