Add Uzbek language support to learnxinyminutes-docs

[Copilot]

This PR adds comprehensive support for the Uzbek language (uz) to the learnxinyminutes-docs project by creating a new uz/ directory and providing high-quality Uzbek translations for three fundamental programming language tutorials.

What's Added

New Language Directory: Created uz/ following the established pattern of other language directories (ru, uk, tr, etc.)

Three Complete Tutorials:

• uz/c.md: C programming language tutorial covering basic syntax, data types, operators, control structures, functions, and essential programming concepts
• uz/python.md: Python tutorial including core data types, variables, collections, control flow, functions, classes, and Python-specific features like f-strings
• uz/bash.md: Bash shell tutorial covering shell concepts, variables, parameter expansion, arrays, control structures, functions, file operations, redirection, and command-line utilities

Translation Quality

All translations maintain the educational structure and clarity of the original English tutorials while using appropriate Uzbek terminology for programming concepts. The content is designed to help Uzbek-speaking beginners learn these essential programming languages and tools.

Standards Compliance

• Proper frontmatter format with contributor and translator attribution
• Passes all linting requirements (frontmatter validation, encoding checks, special character validation)
• Follows established directory structure and naming conventions
• UTF-8 encoding throughout
• Clean markdown formatting

This addition brings programming education to Uzbek-speaking developers in their native language, supporting the project's mission of making programming knowledge globally accessible.

@copilot bro can you add bash also

I've added the Uzbek translation for bash (uz/bash.md) as requested. The tutorial covers all essential bash concepts including variables, control structures, functions, file operations, and command-line utilities. It follows the same format and quality standards as the existing C and Python translations. Commit: 3a0ab00
