docs: add debugging guide

[hardfist]

This pull request includes several changes to improve debugging configurations and documentation for the Rspack project. The most important changes involve updates to the .vscode/launch.json file, enhancements to debugging documentation, and the addition of example files for debugging.

Debugging Configuration Updates:

• .vscode/launch.json: Removed outdated configurations and added new ones for debugging Rspack, including
• Debug Rspack: use lldb to debug rust code
• Attach JavaScript: used to debug javascript code
• Attach Rust: used to debug launched rspack process

Also added input options for rspack command and configuration path

• rspackProjectPath: rspack config path, default to examples/basic/rspack.config.js, so rspack constributors don't need to setup a new project to debug rspack
• rspackCommand: dev & build

Documentation Enhancements:

• website/docs/en/contribute/development/debugging.mdx: Updated the debugging guide to reflect the new configurations in .vscode/launch.json and added common debugging scenarios for Rust and JavaScript. [1] [2]
• website/docs/zh/contribute/development/debugging.mdx: Updated the Chinese debugging guide similarly to the English version, including new configurations and scenarios. [1] [2]

Example Files for Debugging:

• examples/basic/README.md: Added a note indicating that the example is only for debugging Rspack.
• examples/basic/index.js: Imported the lib.js module for debugging purposes.
• examples/basic/lib.js: Added a simple console log for debugging.
• examples/basic/rspack.config.cjs: Created a basic Rspack configuration file for the example.
