docs: Add editor integration guide for Rust development in NuttX

[no1wudi]

Summary

• Added a section on editor integration for Rust development in NuttX, focusing on VS Code and rust-analyzer
• Provides steps to configure .vscode/settings.json to recognize Rust project structure and optional settings for custom target specifications

Impact

• Enhances developer productivity by providing better IDE support for Rust in NuttX
• No impact on existing functionality; the guide is purely informational and configuration-based

Testing

Local doc build

[Experimental Bot, please feedback here]

Yes, this PR appears to meet the NuttX requirements, although some sections could be more detailed.

Strengths:

• Clear Summary: The summary explains the "what" and "why" of the change.
• Impact is Addressed: The impact section covers relevant aspects and clearly states there are no negative impacts on existing functionality.
• Evidence of Testing: A screenshot of a successful doc build is provided.

Areas for Improvement (if applicable, depending on the actual PR):

• Specificity in Summary: While the summary is good, it could be more specific about which functional part of the code is changed (the documentation). Mentioning the specific file path would be helpful.
• More Detailed Testing Information: While the screenshot shows a successful build, providing more context would be beneficial. What command was used to build the docs? What platform was this built on? "Local doc build" is vague. Ideally, follow the requested format with "before" and "after" logs (even if just showing successful builds in both). Even if the change is only to documentation, showing the build commands used strengthens the testing verification.
• Consider "N/A" for Non-Applicable Impact Sections: Explicitly stating "N/A" for sections like "Impact on security" or "Impact on compatibility" (if truly not applicable) can make the PR review quicker.

While the PR seems to meet the requirements, adding the suggested details would improve clarity and completeness.

In the added documentation, I checked for readability and clarity of the new text. I don't have the Rust or VSCode setup to verify the code blocks, but they look reasonable. Commit log looks good. Thanks for helping to improve NuttX documentation!
