fix(files_versions): Use NcDateTime for proper translated version dates

[susnux]

Summary

Basically this contains 3 notable changes:

1. Use NcDateTime instead of moment to fix version dates not being translated correctly
   • Fixes [Bug]: Some translation missing #44950 (comment)
2. Allow version label and date to shrink to make the version entry readable on small screens (see screenshots below)
3. Remove filters and replace them with computed values. Filters are deprecated and will make a migration to Vue 3 harder
