Fix Translation-Badges

shields.io has deactivated the JSONPath array filter. 
Query string of Crowdin badges must therefore now contain fixed position numbers.

See here:
https://shields.io/blog/GHSA-rxvx-x284-4445#2-users-of-dynamic-jsontomlyaml-badges

old:
```
$.progress[?(@.data.languageId=='de-CH')].data.translationProgress
```
new:
```
$.progress.0.data.translationProgress
```
