Docs/link lora training tutorials

[ChuxiJ]

This pull request enhances LoRA training documentation and improves Markdown rendering in the Gradio UI. The main changes add step-by-step LoRA Training Tutorials in multiple languages, update documentation links throughout the project, and improve the Markdown-to-HTML converter to support links in all contexts. Tests are also added to ensure correct link rendering.

Documentation and Tutorial Improvements:

• Added a dedicated "LoRA Training" column and links for all supported languages (English, 中文, 日本語, 한국어) in the multi-language documentation table in README.md.
• Expanded the "Train" section in README.md to include a clear, language-specific table of LoRA Training Tutorials and a reference to advanced CLI training with Side-Step.
• Updated the LoRA training and dataset builder documentation in English, Chinese, and Japanese Gradio UI translation files to include direct links to the new LoRA Training Tutorials and Side-Step documentation. [1] [2] [3]
• Added a prominent reference to the LoRA Training Tutorial in the Gradio Guide for LoRA Training.

Markdown Rendering Enhancements:

• Improved the _md_to_html function in acestep/ui/gradio/help_content.py to support Markdown links ([text](url)) in headings, blockquotes, list items, and paragraphs, rendering them as styled <a> tags that open in a new tab. [1] [2] [3]
• Added tests for link rendering in paragraphs, list items, blockquotes, and headings in help_content_test.py.

This pull request enhances Markdown-to-HTML conversion in the help content module to automatically transform Markdown links into HTML anchor tags with external link styling. It adds corresponding test coverage for the new link rendering behavior across multiple contexts and updates localization strings to reference documentation links.

Changes

Cohort / File(s)	Summary
Markdown Link Processing acestep/ui/gradio/help_content.py	Implements regex-based transformation of Markdown links [text](url) into HTML anchors with target="_blank" attribute across headings, blockquotes, list items, and paragraphs. Modifies internal conversion pipeline without changing public API.
Test Coverage acestep/ui/gradio/help_content_test.py	Adds four new test methods (test_link_in_paragraph, test_link_in_list_item, test_link_in_blockquote, test_link_in_heading) to verify link rendering produces proper anchor elements with href and text content.
Localization Updates acestep/ui/gradio/i18n/en.json, ja.json, zh.json	Updates training section UI strings to include "📖 Documentation" subsections with external documentation links. Adds normalization and latent handling parameter labels in Japanese and extends Chinese training workflow content.

Poem

🐰 Links now hop through markdown bright,
Opening doors in tabs, what a sight!
Documentation guides, in every tongue,
External anchors dance—the code is sung!
New tests ensure each link takes flight,
Web navigation's never been so right! 🌐
