Update cookbook for ESP32 Water Leak Detector (#1369) 

* Update leak-detector-m5stickC.rst

1) The ST7735 display is now natively supported in ESPHome >1.16.0.  Therefore the custom component is no longer needed. Also, ESPHome color handling seems to have changed, so that has been accounted for. Updated the instructions and code to reflect these.

2) Updated URL of esp32 bootloader

3) Added st7735 display docs link to footer

* Update cookbook/leak-detector-m5stickC.rst

https://github.com/airy10/esphome-m5stickC/issues/4
- `M5Stick axp192 custom component <https://github.com/airy10/esphome-m5stickC>`__
This is needed to power up the display. You don't need the st7735 display driver, as it is already included with ESPHome >1.16.0.

I initially had trouble flashing the M5StickC; this is the procedure that I've found to work well with these devices.
You must provide the ESP32 bootloader during the initial flash over USB. Compile your ESPHome binary, and flash it along with the required bootloader (bootloader_dio_80m.bin), `available here <https://github.com/espressif/arduino-esp32/tree/master/tools/sdk/bin>`__, from the commandline (example under macos):
