refactor: remove json-stable-stringify

[bluwy]

Description

Remove json-stable-stringify to reduce bundled dependency size. It was added in #11542

It seems that we only need to ensure the top-level keys of the manifest are sorted. We don't have to do it recursively. We can easily achieve that by sorting the keys manually before stringifying.

Additional context

In the first commit, I updated to sort recursively. In the second commit, I only sorted the top-level keys as that's only needed.

I tested the manifest changes manually.
