[Bug]: package.json of @ngrx/store/testing is incorrect

[ahnpnl]

Minimal reproduction of the bug/regression with instructions:

• Checkout https://github.com/ahnpnl/jest-preset-angular/tree/example-wrong-lib-format (branch example-wrong-lib-format)
• Run yarn install to install project dependencies
• Navigate to e2e/partial-ivy-lib
• Run yarn install
• Open e2e/partial-ivy-lib/node_modules/@ngrx/store/testing/package.json
• Observe that a few lines in this package.json points to non-existed files:

{
  "name": "@ngrx/store/testing",
  "typings": "ngrx-store-testing.d.ts",
  "main": "../bundles/core-testing.umd.js", // THIS IS NOT EXISTED !!!
  "module": "../fesm2015/ngrx-store-testing.mjs",
  "es2015": "../fesm2015/testing.js", // THIS IS NOT EXISTED !!!
  "esm5": "../esm5/testing/testing.js", // THIS IS NOT EXISTED !!!
  "esm2015": "../esm2015/testing/testing.js", // THIS IS NOT EXISTED !!!
  "fesm5": "../fesm5/testing.js", // THIS IS NOT EXISTED !!!
  "fesm2015": "../fesm2015/ngrx-store-testing.mjs",
  "es2020": "../fesm2020/ngrx-store-testing.mjs",
  "esm2020": "../esm2020/testing/ngrx-store-testing.mjs",
  "fesm2020": "../fesm2020/ngrx-store-testing.mjs",
  "sideEffects": false
}

• Open e2e/partial-ivy-lib/node_modules/partial-ivy/testing/package.json. Observe that those lines are not there.

Because of those lines, it causes the issue thymikee/jest-preset-angular#1195

Expected behavior:

The content of e2e/partial-ivy-lib/node_modules/@ngrx/store/testing/package.json should be similar to e2e/partial-ivy-lib/node_modules/partial-ivy/testing/package.json, which is

{
  "name": "@ngrx/store/testing",
  "typings": "ngrx-store-testing.d.ts",
  "module": "../fesm2015/ngrx-store-testing.mjs",
  "fesm2015": "../fesm2015/ngrx-store-testing.mjs",
  "es2020": "../fesm2020/ngrx-store-testing.mjs",
  "esm2020": "../esm2020/testing/ngrx-store-testing.mjs",
  "fesm2020": "../fesm2020/ngrx-store-testing.mjs",
  "sideEffects": false
}

Versions of NgRx, Angular, Node, affected browser(s) and operating system(s):

@ngrx/store version 13.0.1

Other information:

Once correcting the content for package.json like above, Jest won't throw error about "Cannot find module" anymore

I would be willing to submit a PR to fix this issue
