Version Checker for Project Dependencies

[dxvid-pts]

VS Code offers an extension called Dependi that shows if the project is on the latest version of a dependency.
This feature is currently the primary one I miss when using Zed IDE compared to VS Code.

• Checks if dependencies are on the latest available version.
• Supports common dependency files like Cargo.toml, package.json, pubspec.yaml, etc.
• Displays all available versions upon hovering over a dependency.

To further improve upon Dependi, we could integrate a changelog when hovering over dependencies too for languages and ecosystems that maintain centralized changelogs (e.g., Dart packages on pub.dev). This would provide developers with quick context about version updates and would even improve the experience compared to VS Code :-)

For reference, this is the same issue but for Cargo only but I think it should work for all supported language: #20238
