[Snyk] Fix for 2 vulnerabilities

[snyk-io]

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

Snyk changed the following file(s):

• packages/app-defaults/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.

[graphite-app]

This PR introduces a problematic approach to dependency management in a monorepo. Replacing workspace references (workspace:^) with pinned versions (0.1.0 and 0.1.1) breaks the internal dependency structure that workspace references are designed to maintain. These specific versions appear to be quite old and likely incompatible with the current codebase.

The warning in the PR description that "Failed to update the yarn.lock" is a significant red flag - this confirms the changes will cause dependency resolution issues.

A better approach would be to:

1. Update the vulnerable dependencies within the workspace
2. Maintain the workspace:^ references
3. Ensure the yarn.lock file is properly updated

Consider rejecting this PR and addressing the vulnerabilities by upgrading the affected packages within your workspace structure instead.
