Currently, some tests in the `compiler-cli/integrationtest` package fail
on Windows because there are spec files which are not Bazel-generated.
When Bazel runs these tests on Windows, the spec file is resolved to
the actual source file (since there is no runfile symlinking/sandboxing).
This breaks the execution of the CJS spec file since it resides in th
`packages/compiler-cli` source folder which has a `package.json` set to
`type: module`.
We fix this by adding a `package.json` file for the integration test
folder and setting `module` to `commonjs`.
