Cli package option creates skeleton library project with missing configuration file

[antony]

Describe the bug

It looks like if you elect to use neither JS with types or Typescript when creating a package from the CLI, you end up without a jsconfig or tsconfig file.

However, packaging defaults types to true, because it's recommended for the ecosystem, so this file is mandatory.

Reproduction

npm create svelte@latest # select plain JS library project
pnpm i
pnpm build

> Failed to locate tsconfig or jsconfig
