[FEAT] Simplify Confirmation Process

[NeonDaniel]

Objective

Saying "go ahead" and a number in the range 100-999 is cumbersome and can be difficult to parse and remember between the prompt and spoken response.

Initial Implementation Requirements

• Test behavior with a 2 digit number for confirmation
• Consider alternatives (set of quasi-random words, colors, etc.)

Other Considerations

• skill-device_controls/__init__.py

  Line 93 in 6820a0f

  confirm_number = str(randint(100, 999))

• ESL users may find it difficult to complete different confirmation options
