Language Menu doesn't work for news detail pages

As mentioned in the [news documentation](https://docs.typo3.org/p/georgringer/news/main/en-us/Tutorials/ExtendNews/DataProcessing/LanguageMenuProcessor.html), the language menu need this Processor to check if news detail pages are available or not.
Otherwise you will get a link to the news translation even if it does not exist.

To fix this, you have to add:

```
page {
10.dataProcessing {
40 {
as = languagenavigation
addQueryString = 1
}
41 = GeorgRinger\News\DataProcessing\DisableLanguageMenuProcessor
41 {
if.isTrue.data = GP:tx_news_pi1|news
menus = languagenavigation
}
}
}
```

Maybe this can be included in the next update of bootstrap_package?

Start with the linked news documentation and locate the bootstrap_package configuration that assembles the language menu for news detail pages. Compare its current behavior with the supplied TypoScript processor configuration, then verify that unavailable news translations no longer receive links.
