Related tdf#129547: add Excel shortcuts insert time/date in Calc for German UI

For German UI and locale
German layout keyboard (based from https://en.wikipedia.org/wiki/German_keyboard_layout)

https://www.traens.com/tipps/microsoft/datum-uhrzeit-excel.html
indicates:
"
Einfügen eines statischen Datums in Excel
Drücken Sie STRG + . (Strg und Punkt)

Einfügen der aktuellen Uhrzeit in eine Excel Tabelle
Drücken Sie STRG+UMSCHALT+. (Strg, Umschalt, Punkt)
"

so I added (specifically for "de"):
POINT_MOD1 for InsertCurrentDate
COLON_SHIFT_MOD1 for InsertCurrentTime
