Fix cast translation string

[NoRi2909]

In the 'show_lovelace_view' action of the Cast integration there are two fields for specifying the Dashboard URL path and optionally the View URL path.

The description of the latter lacks "URL" so it's easy to misunderstand "View path" as it happened in the German translation that had turned this into "viewing a path".

Proposed change

Fix this by adding "URL" to the second description as well. So we get consistent explanations:

• The URL path of the dashboard to show.
• The URL path of the dashboard view to show.

Note that including "URL" also makes sense as the Dashboard editor in the frontend calls these just "URL".
This might warrant an additional PR for the frontend to use "URL path" there as well, as these are not complete URLs.
