Documentation: Commented all_keys_in_defsrc

[IndigoGollum]

Is your feature request related to a problem? Please describe.

Some of the keys here are unclear in their meaning, like for example "102d". So i've added comments after every line, except where it's a single character with an obvious meaning or where it's something i don't understand.

Describe the solution you'd like.

Replace https://github.com/jtroo/kanata/blob/main/cfg_samples/all_keys_in_defsrc.kbd with my commentated version.

Describe alternatives you've considered.

Get someone who actually understands this stuff to add comments to this document.

Additional context

The fixed file is here: https://pastebin.com/CaT6dGsP

I'd forgotten about this file. It's probably out of date and missing some named keys. Probably better to move the file to a test directory instead of samples directory, and make something new linked in the configuration guide somewhere if further work is done at all.
