…mbracelet#427)

* feat: Adjust `Confirm Buttons` within the Confirm Field

- Added in method to adjust the position of the confirm buttons,
  within the confirm field
- If the user does not adjust the position of the confirm buttons,
  it defaults to the center of the confirm view field
- If the user provides the position of the confirm buttons,
  it overrides the position of the buttons in the confirm view field
