caps_word does not work for German umlauts

[ThomasMader]

I am using caps_word which is working for all keys except for the ones with German umlauts:

ö - Ö (SEMICOLON)
ä - Ä (SINGLE_QUOTE)
ü - Ü (LEFT_BRACKET)

They are defined in my keymap as normal keypresses like this:

"value": "&kp", "params": [ { "value": "SEMICOLON", "params": [] } ]

I also had the problem that my continue-list did not work for them but I found out that it works by using the long name instead of the short one.

SEMI -> SEMICOLON
SQT -> SINGLE_QUOTE
LBKT -> LEFT_BRACKET

But the caps_word still doesn't work with the full names. It continues writing the lower case versions for the umlauts when the caps_word is enabled.

ZMK version: bb48661

#1742 would provide a way to fix this.
