Here plugin does not support authentication via apiKey

The usage of app_id and token is deprecated now. In addition the urls have chnages as well as the protocol for the request (now it's https).

The problem was described in https://stackoverflow.com/questions/60544057/qt-qml-map-with-here-plugin-how-to-correctly-authenticate-using-here-token.

In the same post, the user eyllanesc has provided a patch for Qt 5.14 that it's compatible with Qt 6 (https://github.com/eyllanesc/stackoverflow/blob/master/questions/60544057/Qt5.14/update-HERE-Qt5.14.patch)
