[Grid Config] Listing of the saved configurations should include the favorite information

[vin0401]

In the UI we want to offer the user the possibility to (un-)favorite configurations based on the list of the available configurations:

For this case it would be useful for us to include the favorite information in our listing endpoint:
/pimcore-studio/api/assets/grid/configurations/{folderId}

Also we are currently missing an option to unfavorite a configuration without sending an update for a specific configuration over the update endpoint: /pimcore-studio/api/assets/grid/configuration/update/{configurationId}

Either we should allow the update endpoint to accept partial updates, like a combination out of id and favorite.
Or rethink the currently available endpoint for setting a favorite: /pimcore-studio/api/assets/grid/configuration/set-as-favorite/{configurationId}/{folderId}

@vin0401 what about if we toggle with /pimcore-studio/api/docs#/Asset%20Grid/asset_set_grid_configuration_as_favorite and then consequently also rename it a bit to /pimcore-studio/api/docs#/Asset%20Grid/asset_toggle_grid_configuration_favorite?

@mattamon - yep, an endpoint for toggling should totally do it. :)
