[Snyk] Fix for 6 vulnerabilities

[q1blue]

Snyk has created this PR to fix 6 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.

Walkthrough

This pull request updates the dependency management strategy for the app-defaults package by transitioning from workspace protocol references to explicit version numbers for three Backstage packages. The changes replace workspace:^ references with specific versions: 0.1.0 for @backstage/core-app-api and @backstage/core-components, and 0.1.1 for @backstage/theme. This modification suggests a shift from local workspace dependencies to published package versions, which is typically done as part of release preparation or to standardize dependency management across the project.

Changes

File(s)	Summary
packages/app-defaults/package.json	Updated three Backstage package dependencies from workspace:^ to explicit versions: @backstage/core-app-api and @backstage/core-components to 0.1.0, and @backstage/theme to 0.1.1.
