Pull request overview

This pull request updates the German localization file to replace the German word "Verteilung" with "Distribution" (the English word used as a loanword) throughout the WSL codebase. This change addresses user feedback in issue #13968 regarding the German translation.

Key Changes:

• Systematically replaced "Verteilung" with "Distribution" across all user-facing German strings
• Updated compound words like "Verteilungsname" to "Distributionsname"
• Maintained consistency with existing German compound word patterns (e.g., "Legacy-Distribution", "Distributions-ID")
