Formatting: Transform “ẞ” for German locales in remove_accents().

The capital Eszett was standardized in German orthography in 2017, DIN 5008, but WordPress has only been transforming the lowercase version.

This patch adds the uppercase variant to the list and transforms it to “SS” for more-appriate slug and permalink generation.

Props apermo, dmsnell.
Fixes #64821.
