ESPHome examples missing required option 'invert_colors'

[pfrenssen]

ESPHome 2024.9.0 introduced a new required invert_colors option for the ili9xxx display (Ref. esphome/esphome#7292).

Currently the examples for ESPHome fail with the following error:

$ esphome run yellowtft1.yaml
INFO ESPHome 2024.12.4
INFO Reading configuration yellowtft1.yaml...
...
Failed config

display.ili9xxx: [source yellowtft1.yaml:118]

  'invert_colors' is a required option for [display.ili9xxx].
