Sorted remotes for deterministic builds

[andrebaerlocher]

Hiya, first time potentially contributing to such a huge project, so I'd rather ask instead of imposing weird ideas, opening a PR, etc.

The reason is, I've currently Ko for SvelteKit in the works, i.e. an image builder. And, in order to make it deterministic, the remotes would need to be sorted.

Is there a need or want for such a feature (or tool)? There seems to be some want for deterministic behaviour and builds according to some discussions.

The PR would be really small, one addition to packages/kit/src/core/generate_manifest/index.js:

const sorted_remotes = [...remotes].sort((a, b) =>
	a.hash < b.hash ? -1 : a.hash > b.hash ? 1 : 0
);

Then replace remotes in

${remotes.map((remote) => `'${remote.hash}': ${loader(join_relative(relative_path, `chunks/remote-${remote.hash}.js`))}`).join(',\n')}

with sorted_remotes

Plus, three tests for packages/kit/src/core/generate_manifest/index.spec.js to verify/ascertain/make sure and changeset.
