[automower] Bridge connection issue due to possible change in authentication API

Hi,

my Automower Connect Bridge can no longer communicate with the husqvarna cloud. I think it is due to a change in the Auth API, it now requires an application secret and no longer a username and password.

For example:

curl -X POST -d "grant_type=client_credentials&client_id=XXX_Application_Key_XXX&client_secret=XXX_Applications_Secret_XXX" https://api.authentication.husqvarnagroup.dev/v1/oauth2/token
