[fix] Refactor yeetube-download--ytdlp

- Used 'executable-find' to validate the presence of 'yt-dlp' and 'torsocks' binaries.
- Separated the construction of each part of the command for better readability.
- Utilized 'mapconcat' to assemble the final command, removing nil values and unnecessary spaces.
- Factored out string literals in the command construction and reduced unnecessary string concatenation.
