[Snyk] Fix for 1 vulnerabilities

[q1blue]

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

Snyk changed the following file(s):

• plugins/catalog-backend-module-puppetdb/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.

Code Review

This pull request, automatically generated by Snyk, attempts to fix a vulnerability by updating dependencies. However, the proposed changes are incorrect for this monorepo setup. It replaces workspace:^ references with pinned versions, which breaks the internal dependency linking of the monorepo. More critically, it downgrades some key @backstage packages to much older major versions, which will almost certainly introduce breaking changes and instability. The PR also notes that it failed to update the yarn.lock file, further indicating that the proposed changes are invalid. I strongly recommend rejecting these changes and addressing the vulnerability by updating the transitive dependency (tar) correctly within the monorepo structure.

[gemini-code-assist]

These automated dependency updates are incorrect and should be rejected.

1. Breaks Monorepo Dependency Linking: The change from workspace:^ to pinned versions is incorrect for a Yarn workspace-based monorepo. It severs the link to local packages, causing this module to use potentially outdated, published versions instead of the current source code from within this repository.

2. Major Version Downgrades: This change introduces severe downgrades for critical packages, which will likely break the application:

   • @backstage/catalog-model is downgraded from its workspace version 1.4.1 to 0.1.1.
   • @backstage/plugin-catalog-node is downgraded from its workspace version 1.4.1-next.0 to 1.0.0.

3. Incomplete Change: As noted in the PR description, yarn.lock was not updated, which means the dependency tree is unresolved and likely broken.

Instead of accepting this change, the underlying vulnerability in the tar package should be resolved by updating it across the entire monorepo, while preserving the workspace:^ protocol for internal packages.
