fix: widen range for optional webpack dependency

[sonallux]

Summary

When installing jest-preset-angular with angular 12.0.3, two webpack versions are installed in node_modules:

• webpack 5.36.2 from jest-preset-angular
• webapck 5.38.1 from @angular-devkit/build-angular

This PR widens the range of the optional webpack dependency, so the package manager can deduplicate the webpack version. This will result in faster install times and smaller node_modules folder.

Test plan

All tests are green.

Does this PR introduce a breaking change?

• Yes
• No

Angular 9 10 (possibly 11 too) don’t have webpack 5. I think it’s better put something like ^4.0.0 || ^5.30.0 or just >=4.0.0

Angular 9 with webpack 4 https://github.com/angular/angular-cli/blob/6770841e07c1c5c980edbde6232fa02da68e6c7b/packages/ngtools/webpack/package.json#L32

Angular 12 with webpack 5 https://github.com/angular/angular-cli/blob/dc6849c7e966a8ade916aa4371b47db7501cb3d1/packages/ngtools/webpack/package.json#L29

I wasn't aware that Angular 9, 10 and 11 are also still supported. I am going to change the range to ^4.0.0 || ^5.30.0.
