[Keymap] plattfot - Update and fix issue with DBL_TAP (#9666)

- Fix typo in the default layout.
- Move esc and del to the navi layer.
- Fix issue with oneshot layers and double tap aka DBL_TAP.
- Add caps lock to the raise layer.

Was relying on a broken behavior for the double tap to work with
oneshot keys, i.e. the oneshot layer not being cleared after a key
press in `process_record_user`, which allowed me to first press an
oneshot key, then double tap and then a key. With the behavior fixed,
this no longer works. As the oneshot layer will be cleared when double
tap is pressed.

To make double tap useful again. I changed that any of the layer keys
does not clear the double tap. Which allows me for example to first
press double tap, then an oneshot key and then a key. So now I'm able
to type my double symbols again.
