Use frontend state name with localization in automation trigger and condition descriptions

[krazos]

The auto-generated description of automation triggers and conditions reports the actual (backend) state of the entity. For consistency with the new state and attribute value auto-completion, it would be better for the auto-generated description to instead use the frontend state name with localization.

Example 1 (Trigger - state of binary sensor w/ device_class = door):

When Front Door changes from on to off should become When Front Door changes from open to closed

Example 2 (Condition - state of person):

Confirm John is not_home should become Confirm John is away
