docs: Add term annotations for destructure and binding terms in localization files

[Copilot]

This PR reviews and updates the Chinese translations in locales/docs/typst-docs.toml and related detailed TOML files to properly annotate the destructure, destructured, and binding terms according to the localization guidelines.

Changes Made

Added New Terms to Reference

• Added destructure → "解构" to docs/terms.toml
• Added destructured → "被解构的" to docs/terms.toml
• Added binding → "绑定" to docs/terms.toml

Updated Translation Files

Updated 6 TOML files with proper term annotations following the format 「translated_term」（[original_term](#x-term-original_term)）:

Main translations file (typst-docs.toml):

• Fixed array enumeration description to properly annotate "destructured" and "binding" terms
• Updated page binding descriptions in margin contexts
• Ensured only first occurrence of each term is annotated per text block

Detailed files:

• reference.scripting.body.toml: Updated bindings and destructuring section titles and content
• reference.syntax.body.toml: Annotated "binding" in syntax reference table
• tutorial.advanced-styling.body.toml: Annotated "bound" in variable binding context
• reference.svg.svg.details.toml: Annotated "binding" in resolution independence context

Translation Guidelines Followed

• Only the first occurrence of each term is annotated within each translation text
• Used proper Chinese quotation marks「」for technical terms
• Maintained original technical accuracy and meaning
• Distinguished between different contexts (let binding vs page binding vs operator precedence)

All TOML files validate correctly after the changes.

Fixes #27.
