[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.

Vulnerabilities that will be fixed with an upgrade:

[graphite-app]

The proposed dependency changes introduce significant issues by replacing workspace references with pinned, outdated versions. Changing workspace:^ to specific versions (0.1.0 and 0.1.1) breaks the local development workflow and module linking that the workspace references provide.

These versions are extremely old and incompatible with the current codebase. The warning about failing to update yarn.lock confirms these changes aren't properly resolved in the dependency tree.

To properly address the vulnerabilities:

1. Maintain the workspace:^ references
2. Update the underlying dependencies that contain http-proxy-middleware in the project root
3. Let Yarn's workspace resolution handle propagating the fixed versions

This preserves the monorepo structure while addressing the security issues in a way that won't break the application.
