svelte-preprocess 5 is available

[canadaduane]

I'm new and was following the directions from the readme to get started. I believe svelte-preprocess version 4 is required at the present time, but "latest" now defaults to 5.0. It may be helpful to others to update the readme to something like this:

npm install --save-dev svelte-preprocess@4 sass postcss
# -- or --
yarn add --dev svelte-preprocess@4 sass postcss
# -- or --
pnpm add --save-dev svelte-preprocess@4 sass postcss

Did you face any problems when installing v5? It seems to me that the breaking changes shouldn't affect us since we recommend installing sass and not node-sass, and while we don't explicitly specify a minimum node version, I doubt anyone who uses Svelte(Kit) has Node.js earlier than v14.

Anyways, after the WIP migration to SvelteKit (particularly, the migration from Sass to CSS), we should hopefully not need any of these dependencies.

It was more of a warning than a problem:

Ah, right, this should be harmless. We just need to update the allowed version range in the peer dependencies.
