[Snyk] Fix for 4 vulnerabilities

[snyk-io]

Snyk has created this PR to fix 4 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• plugins/periskop-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:

Walkthrough

This PR updates the dependency management strategy for the periskop-backend plugin by replacing workspace protocol references with explicit version pinning. Three Backstage packages are affected: backend-common (pinned to 0.25.0), backend-plugin-api (pinned to 1.6.1), and config (pinned to 0.1.1). This transition from monorepo workspace dependencies to specific versions ensures consistent dependency resolution across different environments and typically indicates preparation for independent package publication or distribution outside the monorepo context.

Changes

File(s)	Summary
plugins/periskop-backend/package.json	Replaced workspace protocol references with pinned versions for three Backstage dependencies: @backstage/backend-common to 0.25.0, @backstage/backend-plugin-api to 1.6.1, and @backstage/config to 0.1.1.
