Describe needed settings specific to Joy-It RB-TFT1.8"(v2) ST7735 display

**Describe the problem you have/What new integration you would like**

I would like to add additional info for setting up this specific display to the ST7735 page, as I had some trouble with it.
https://esphome.io/components/display/st7735.html
The description would specify the needed additional component settings to get it to work properly. Namely the color mode and the display model.

**Please describe your use case for this integration and alternatives you've tried:**

The Joy-It RB-TFT1.8" ST7735 requires BGR color mode and INITR_GREENTAB model to be selected, none of which is mentioned in any documentation. For the convenience of future users, this information would save time and effort not only for them but also the supporting people on the discord.
The page could also feature an example section for this purpose.
