Update TX-Ultimate-Easy-ESPHome_core.yaml

Solves #20

I will use this picture as a reference:

![LED numbers from Tasmota](https://templates.blakadder.com/assets/device_images/sonoff_tx_ultimate_T5-86MAIN-V1-0-7-20221108.webp)

Currently, when using a 3-gang device, the following LEDs are currently in use:

| Button/Relay | LED<br>Bottom | LED<br>Top |
| :--: | :--: | :--: |
| 1 | 12 | 22 |
| 2 | 10 | 24 |
| 3 | 8 | 26 |

I will change to the following:
| Button/Relay | LED<br>Bottom | LED<br>Top |
| :--: | :--: | :--: |
| 1 | 13 | 21 |
| 2 | 10 | 24 |
| 3 | 7 | 27 |
