[DOC] Missing LED_MATRIX_INDICATOR_SET_VALUE

[iamdanielv]

Issue Description

The documentation for LED Matrix references "a special macro to help make this easier to use: LED_MATRIX_INDICATOR_SET_VALUE(i, v)."

But I can't find that macro in the current main branch of the code.

It was pretty trivial to write:

#define LED_MATRIX_INDICATOR_SET_VALUE(i, v) \
    if (i >= led_min && i < led_max) {       \
        led_matrix_set_value(i, v);          \
    }

It is confusing to have the documents reference code that doesn't exist.

I suggest to either :

• remove the mention of the macro, or
• put the macro back in the led_matrix.h file

I can create a PR with the changes if it's ok with the maintainers.
