fix(layout): layout emulator values modified according to schema (@m4dd0c)

[m4dd0c]

Description

Some Layout Emulator values were not aligned with the current schema.
So they were changed accordingly.

Checks

• Adding a language or a theme?
  • If is a language, did you edit _list.json, _groups.json and add languages.json?
  • Changed layouts/_list.json

Closes #5948

I tested the three layouts with the code before #5649 and it was broken as well. So I guess renaming the layouts is the right way to solve this.

Hi @fehmer, I've submitted another pull request that includes validation implementation along with some renaming. Could you please take a look and let me know if any changes are needed?

I would like to respect the original names chosen by the layout creators. Instead of changing the layout names just update the layout schema in the contracts package to allow for -. (just duplicate the keymap layout schema into layout schema)
