Pull request overview

Adds a new Portuguese (pt) translation page for the JavaScript “Resources” documentation, aligning the pt locale with the existing English resources.md content and structure.

Changes:

• Introduces content/pt/docs/languages/js/resources.md with localized front matter and translated content for Node.js resource detection (process/env/container).
• Preserves the same shortcodes, section anchors, and reference-style links used by the English source to maintain consistent site behavior/navigation.
