TS Error in compiled dts file due to missing optional dependency `stylelint`

[qwqcode]

Describe the bug

The stylelint is an optional dependency, but dist/esm/types.d.ts imports it as required.

package.json#L78-L80

src/types.ts#L74

Consequently, if stylelint isn't installed, consumers without skipLibCheck (tsconfig.json) enabled will encounter a TypeScript error reported in the declaration files within their node_modules directory from the package.

---

node_modules/vite-plugin-checker/dist/esm/types.d.ts:4:28 - error TS2307: Cannot find module 'stylelint' or its corresponding type declarations.

Reproduction

1. stylelint is not installed (as it's an optional dependency).
2. tsconfig.json does not have skipLibCheck: true set (it's default).
3. perform type checking

Expected behavior

expect no TypeScript type errors

Additional context

Consider making stylelint a required dependency or finding an alternative method to import the stylelint type.

One solution is to add // @ts-ignore to the previous line of import * as Stylelint from 'stylelint', but after I tried it, the packaging tool always removes the comment. 😢
