[Snyk] Fix for 2 vulnerabilities

[anaconda-security-bot]

Snyk has created this PR to fix 2 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• packages/_metapackage/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.

🦉 Uncaught Exception

[anaconda-security-bot]

This upgrade to version 7.0.0 for @jupyter-notebook/help-extension and @jupyter-notebook/ui-components represents a complete architectural overhaul and is a high-risk migration.

Jupyter Notebook 7 is a major rewrite, rebuilt from the ground up using JupyterLab components. This change introduces significant breaking changes and is not backward-compatible with the classic Notebook architecture or its extensions.

Key Breaking Changes:

• New Extension System: The frontend is now based on JupyterLab. Any existing extensions, customizations, or direct usage of the old UI components are incompatible and must be migrated to the new JupyterLab extension system.
• Component Rewrite: The @jupyter-notebook/ui-components package is part of this new architecture. Any previous usage is invalid and requires a complete rewrite against the new component library.
• Package Structure: The changelog indicates that internal packages were restructured. For example, @jupyter-notebook/help-extension was split into multiple plugins, which will break any direct imports or dependencies.

Recommendation:
This is not a routine version bump. Treat this as a major migration project. Developers must rewrite any custom frontend code, themes, or extensions using the new APIs and architecture provided by JupyterLab and Notebook 7. For backward compatibility, the classic Notebook v6 interface is available as a separate nbclassic package.
