German spelling errors are not recognized/displayed

[AdiWeit]

Note: It is highly recommended to follow the instructions at https://valentjn.github.io/ltex/vscode-ltex/contributing.html#how-to-report-bugs and use the LTeX: Report bug in LTeX command from within Visual Studio Code. Per the contribution guidelines, deleting parts of the template or not filling in vital information may result in the issue to be immediately closed as invalid.

Describe the bug
Spelling errors in a German text (typed markdown for example) will not be recognized or at least not displayed as an error.

Steps to reproduce
Steps to reproduce the behavior:

1. Create a new document
2. Set the language mode to Markdown
3. enter the text Deshalb ist die Leitfrage dieser Arbeit, warum C# entwicklet wurde, wenn es doch Java schon gab. or something else with spelling errors
4. See error (the spelling entwicklet for example will not be marked, although it should obviously be entwickelt)

Expected behavior
It would be expected to be marked as an error. Maybe there should even be a quick fix to the problem. The expected behavior is pretty much what the language tool "demo" on their website does if you put the same text in there.

Sample document
If the bug occurs for a specific document (e.g. LaTeX), please paste it here. If your document is very long or confidential, please create and attach a smaller example for which the bug still occurs so that we can reproduce it.

Deshalb ist die Leitfrage dieser Arbeit, warum C# entwicklet wurde, wenn es doch Java schon gab.

LTeX configuration
Please paste all configuration settings starting with ltex. from your settings.json. You can help us by temporarily removing some irrelevant settings from your settings.json and see if the bug still occurs.

I have the same issue and the same log file output.

Setting the LTex language from de to de-DE solves the issue.
