typescript ^5.0.0 should be included in peerDependencies or direct dependencies

[woss]

Describe the problem

the tweak_types method will try to get the 4 new methods that are available in the TS 4.8.0+ https://www.typescriptlang.org/docs/handbook/release-notes/typescript-4-8.html and fail without the error code. This is OK since this will not spam the user output, unfortunately, many people ended up wondering why the types are not created from the load functions and this is not written anywhere.

Furthermore, the typescript that is imported in the ts.js will fail to load the local typescript when in the workspace (monorepo).

Describe the proposed solution

add the peerDependency to the minimum of 4.8.0 so the package managers correctly install it with the sveltekit

i found an ugly solution manually symlinking the correct typescript path to the @sveltejs/kit/node_modules

I think this should be considered since we want to have the types created.

I believe it's intended that TypeScript 5 is required: https://kit.svelte.dev/docs/migrating-to-sveltekit-2#updated-dependency-requirements

Perhaps you upgraded an older project and missed this?

[woss]

hi @benmccann it works as it should on 4.9.5. thing is that if there are other packages in the monorepo that have lower than 4.8 the sveltekit will not load typescript correctly

[woss]

then we can also add the typescript ^5.0.0 as peerDependency
