doc: Add link to login event trigger example

danielgustafsson · danielgustafsson · commit 94902b146fae · 2024-10-02T12:24:39.000+02:00
The login event trigger is not listed on the trigger firing matrix since it's not fired by a command. Add a link to the example code page similar to how the other event triggers link to the matrix.
