The translation maintains the structure and formatting of the original file and includes all sections, ensuring that Turkish-speaking users can access the documentation in their native language.

Does this PR introduce a breaking change?

Other information

This PR enhances the accessibility of the documentation by providing a Turkish translation (readme_tr.md). It aligns with the structure and content of the original Readme.md file, ensuring consistency across translations.
