[Snyk] Fix for 1 vulnerabilities

[anaconda-security-bot]

Snyk has created this PR to fix 1 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• packages/tree-extension/package.json

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

⚠️ Warning

Failed to update the yarn.lock, please update manually before merging.

🦉 Directory Traversal

[anaconda-security-bot]

This set of upgrades includes a major and high-risk update to @jupyter-notebook/tree as part of the migration to Jupyter Notebook 7, alongside low-risk stabilization updates for other JupyterLab packages.

High Risk: @jupyter-notebook/tree@0.0.0-use.local → @jupyter-notebook/tree@7.0.0

This upgrade represents a move from a non-standard local version to the official Jupyter Notebook 7 release. This is a complete architectural overhaul, not a simple version bump.

Key Breaking Changes:

• New Architecture: Jupyter Notebook 7 is rebuilt from the ground up using JupyterLab components. The classic extension system and APIs from Notebook v6 are no longer compatible.
• User Interface: While the user experience is designed to be familiar, the underlying components, including the file browser provided by @jupyter-notebook/tree, are entirely new. Any code that interacts directly with the old UI or its APIs will break.
• New Features: This version inherits many features from JupyterLab, including a visual debugger, real-time collaboration, and a new theming system, which underscores the magnitude of the change.

Recommendation: This is a significant migration. All custom extensions and integrations with the classic Jupyter Notebook front end must be rewritten for the new JupyterLab-based architecture. For backward compatibility, the project provides NbClassic as a temporary solution to run the Notebook 6 interface.
