51-58: Make UART framing fields explicit in the example config.

The prose says 8 data bits and 1 stop bit are required; adding those keys directly to the YAML example avoids ambiguity for copy/paste users.

Suggested tweak

 uart:
   id: ac_uart
   tx_pin: GPIO1
   rx_pin: GPIO3
+  data_bits: 8
   baud_rate: 2400
   parity: EVEN
+  stop_bits: 1

58, The example UART YAML in the Mitsubishi CN105 doc omits framing fields;
update the uart example block (the mapping with id: ac_uart, tx_pin: GPIO1,

In `@src/content/docs/components/index.mdx`:
- Line 696: The ImgTable row added in the components index uses a relative image
filename ("mitsubishi_electric.png") which violates the ImgTable convention;
update the image reference in the array entry (the row for "Mitsubishi CN105
Climate") to the absolute path under /images/ (e.g., "/images/…") so it points
to the file stored in /public/images/, ensuring the ImgTable entry uses the
absolute image path convention.
