feat: add short aliases (pm, packageManager, lang, lang, cache) for configuration keys

[IT-WIBRC]

Description

This PR introduces short aliases for core configuration properties to make the dk config command faster and more ergonomic.

The following short keys are now supported for both reading (dk config [keys...]) and setting (dk config --set):

Full Key	Short Alias
defaultPackageManager	pm, packageManager
language	lang, lg
cacheStrategy	cache

Key Changes:

• Configuration Aliases: Enables setting and getting configuration values using short aliases (e.g., dk config pm pnpm).
• Testing: Adds new integration tests to ensure full coverage of the new short keys in the dk config command.
• Documentation: Updates the French and English translation files and the README.md to clearly document the supported keys and their aliases.
• Cleanup: Removes the redundant dk config cache command documentation, as cache management is now fully integrated into dk config update.
