Support opening app from template widget

[potchin]

Is your feature request related to a problem? Please describe. I have a text-based widget on my home screen which shows states of various HA entities. Frequently I'll want to open HA after seeing a state in the widget (eg I left a light on), it would be great to be able to tap the widget itself to launch the HA app.

At the moment the only time the widget supports a tap action is when there has been an error, which causes a retry. I suggest this is retained and the new functionality is only applied when the widget is in a non-error state.

Describe the solution you'd like To be able to open the HA app by clicking on the text widget.

Describe alternatives you've considered, if any

thats incorrect it also performs an update when there is no error shown to the user.
