fix(dev): include cssBundleHref in manifest hash

[markdalgleish]

Fixes #6369

The cssBundleHref value wasn't being included in the hash in the manifest file name. This means that CSS bundle changes weren't busting the manifest cache. I've also refactored the code to try to avoid this issue coming back when further changes are made to the manifest structure.

I've refactored the code here to help people avoid the mistake of adding a new value to the manifest but forgetting to include it in the hash.
