This pull request updates troubleshooting documentation for Avalonia UI styles in English, Russian, and Simplified Chinese. The main changes clarify style application, update terminology, improve code samples, and enhance explanations of style priority and theme references.

Documentation improvements:

• Updated all XML style examples to use the correct Setter syntax instead of Style Property for consistency and clarity in both English and Russian docs.
• Replaced legacy HTML tables with markdown tables for the BindingPriority enum, corrected terminology (e.g., "Template" instead of "TemplatedParent"), and clarified comments in all languages. [1] [2]

Explanations and terminology:

• Improved descriptions and terminology in the Simplified Chinese guide, making explanations more accurate and easier to understand (e.g., clarifying style precedence, selector matching, and priority rules). [1] [2]
• Updated theme references from "Default" to "Simple" where appropriate, and clarified which themes the examples refer to in English, Russian, and Chinese docs. [1] [2] [3] [4]

Clarifications on style application:

• Enhanced explanations about why certain style setters may be ignored due to template behavior, and how to correctly target elements like ContentPresenter for state-dependent styling. [1] [2] [3]

These changes improve clarity, consistency, and accuracy in the troubleshooting guides for Avalonia UI styles.
