…ssistant#135446)

* Make "Urgent message" selector consistent, use "Bring!" as name

- Replace one occurrence of "bring" with the brand name "Bring!"
- Change description of action to third-person singular for consistency in Home Assistant
- Make all occurrences of the selector "Urgent message" consistent (in sentence case) so they all get consistent translations, too
- Change one related error message to refer to the UI name of the required "Article" field

* Changed ` to '  to avoid Regex problems

* Reverted change to notify_missing_argument_item

Reverted to avoid failing test

* Reverted change to "bring"

* Add "is" to description of "Article"
