feat(language): Add support for Turkish language

[omerfaruk-aran]

Summary

This PR includes the following changes:

1. Fix for Cover State Logic:

   • Adjusted the _current_state method for better accuracy in determining the cover's state.
   • Improved handling of the cover's position to properly stop when reaching target positions.

2. Turkish Language Support:

   • Added tr.json for Turkish language support, improving localization for users in Turkey.

Changes

• File Updated:
  • custom_components/localtuya/cover.py
    • Enhanced state and position logic for covers.
  • custom_components/localtuya/translations/tr.json
    • Added Turkish translations.

Why is this needed?

• The cover control logic previously had issues where directional buttons (up and down) did not properly reflect state changes. This fix ensures accurate state updates.
• Turkish language support was missing, which limited the accessibility for Turkish-speaking users.

Additional Notes

• The code has been tested with both directional buttons and position sliders to ensure functionality.
• Translations have been added for all relevant strings to ensure a seamless user experience.
