Replace deprecated rgb_order with channel_colors

[TrevorSchirmer]

ESPHome 2026.8.0 replaces rgb_order / is_rgbw / is_wrgb with a single channel_colors key on esp32_rmt_led_strip (esphome#18474).

channel_colors takes each of R, G, B exactly once, optionally with a single W; the value is case-insensitive. No behaviour change — grb and GRB are equivalent, uppercase to match the ESPHome docs.

Poem

A rabbit updates version signs
And tunes the LED lines
Green, red, blue now hop in place
Two configs share the setting’s grace
New ESPHome rules are clear
The glowing path is ready here

Verified against upstream rather than the description: channel_colors landed in ESPHome 2026.8.0 (esphome#18474), and rgb_order still validates but is marked for removal in 2027.3.0. validate_channel_colors uppercases its input and channel_colors_struct derives the same r/g/b indices, so GRB here is byte-identical to the previous grb. No behaviour change and no change to the compiled binary.

Every esp32_rmt_led_strip block in this repo is covered. I pushed one commit on top bumping min_version to 2026.8.0: devices adopted through the ESPHome dashboard track this repo at HEAD with no pinned ref, so without it an adopter on an older ESPHome would hit Unknown option channel_colors inside a file they never wrote. ESPHome merges remote packages and checks min_version before component schemas load, so the bump surfaces the right error instead.

CI green on stable, beta and dev.
