[keyboard] added Adelheid (#9734)

* readded adelheid files

* reworked keymaps

- moved my personal keymap to a new folder
- added a new default keymap

* removed unnecessary backslash

* reenabled command rule

* bumped device number

* fixed layout for configurator

* applied suggestions from code review

+The Adelheid is a 75% Alice-like keyboard. It's a fork of the [Arisu](https://github.com/FateNozomi/arisu-pcb) by FateNozomi and is open-source as well.
+
+* Keyboard Maintainer: [floookay](https://github.com/floookay)
+* Hardware Supported: Adelheid PCB [Rev2.0]
+* Hardware Availability: [PCB-, case- &amp; wrist rest files](https://github.com/floookay/adelheid)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make adelheid:default
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
