[Bug] GMMK2 65% ANSI - LED coordinates misaligned (and potential fix)

Describe the Bug

When using reactive effects (especially column-based, like RGB_MATRIX_SOLID_REACTIVE_CROSS), there is a noticeable LEDs misalignment, mainly on a bottom row. For example, when pressing "RAlt" with cross effect enabled, a column from "M" to "8" is lit. and not from ">" to "0" as expected.

The values in gmmk/gmmk2/p65/ansi/ansi.c:g_led_config are the cause: for example, Alt_R and M keys share the exact same X coord, which is clearly incorrect.

I found a top-down picture of the keyboard, cropped it and roughly translated LED pixel coordinates to QMK's standard range. With those values put into g_led_config, reactive effects look in place, and there is no bottom row misalignment.

The resulting g_led_config is the following. I can create a pull request, if this solution is confirmed to be correct.

led_config_t g_led_config = {{
