This update highlights numerous improvements to Nushell's documentation. Hustcer contributed significantly by updating and proofreading Chinese translations, adding Turkish support and translation guides. Other contributors addressed various issues, including fixing broken links (reillysiemens), clarifying titles (merelymyself), updating content on tables (Yethal), loading data (morzel85), and aliases (stormasm). Typos were corrected (raboof), PATH configuration was documented (rgwood), table concatenation was fixed (Sygmei), and a `cd` example was improved (Cyborus04).
