[Snyk] Security upgrade @backstage/core-app-api from 0.0.0-use.local to 1.1.0

[q1blue]

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

Snyk changed the following file(s):

• packages/test-utils/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.

Setting @backstage/core-app-api to 1.1.0 will cause Yarn to stop using the local workspace package (currently packages/core-app-api is 1.9.1-next.0) and instead pull an older published copy, which can introduce dependency skew/duplicate instances—was that intended?
