German Umlaute just like in US International Alt Gr (Linux, Windows)

[SeoliteQ]

Just switched from many years of Linux and Windows to macos and wanted to set up German umlaute without installing a separate keyboard layout in macos (tried that first, but some apps started crashing every now and then, hence here I am).

Found the "German Umlaut" keymap on karabiner's complex modification rules and decided to modify it as it uses a, o and u as the initial key while I am used to q, p and y being used for this.

Code is below for anyone wanting to stick to the linux/windows behavior to reach ä, ö and ü.
