Improve redirects for language packs
I think the download of language packs can be a bit improved. Current situation
- Download of https://typo3.org/fileadmin/ter/n/e/news-l10n/news-l10n-de.zip through backend
- Redirects to https://extensions.typo3.org/fileadmin/ter/n/e/news-l10n/news-l10n-de.zip
- Redirects to https://extensions.typo3.org/fileadmin/l10n/n/e/news-l10n/news-l10n-de.zip
so why not redirect 1st to last?
