docs: add Turkish localization (README.tr.md and translation refinements)

[luluwux]

Following our discussion in issue #23, I've completed the Turkish localization:

README.tr.md: Created a high-quality translation based on the automated template but manually refined for better readability and technical accuracy.

translation.json: Refined existing phrases to make them sound more "native" and consistent with developer terminology (e.g., using "Repository Secrets" and natural time indicators).

Localization: I've also translated the "Important" notice to ensure a fully localized experience for Turkish developers.

Ready for review. Thanks for this awesome project! 🚀

Thanks for your patience with the updates! Turkish is a very nuanced language with many ways to express the same idea, so I wanted to make sure the phrasing felt completely natural rather than like a direct translation. This should be the final version now.
