* add german translation of visualbasic-de.vb
* apply kind suggestions by @nbehrnd
Update and rename visualbasic-de.vb to visualbasic-de.html.markdown
* use compact link with label
Markdown allows a shorter definition of a link with a label eventually
displayed e.g., after the conversion by pandoc to yield a html file.
The equivalence in the result was checked with pandoc (3.1.9) by
pandoc -s -i visualbasic-de.html.markdown -o test.html
subsequently displayed by firefox (version 115.6.0 esr).
