[Snyk] Fix for 3 vulnerabilities

[snyk-io]

Snyk has created this PR to fix 3 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• plugins/example-todo-list-backend/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:

	Issue	Score

[graphite-app]

Replacing workspace references with fixed versions disrupts the monorepo dependency management pattern. This approach can lead to version conflicts since the PR description indicates the yarn.lock update failed.

A more effective approach would be to:

1. Keep the workspace:^ references intact
2. Update the vulnerable packages in the root package.json instead
3. Run yarn to regenerate the lockfile properly

This maintains the monorepo integrity while still addressing the security vulnerabilities identified by Snyk.
