Type declaration is messed up with JSON imports

[hyrious]

Environment

Node.js v22.5.1

Reproduction

See this type declaration file in @unocss/preset-icons: https://hyrious.me/npm-browser/?q=@unocss/[email protected]/package/dist/core.d.ts:101

Describe the bug

Additional context

I myself solved this problem by adding a custom rollup plugin that replaces the JSON file with a transformed valid JS(TS) file so that rollup-plugin-dts can handle it like other files: https://github.com/hyrious/dts/blob/main/src/index.ts#L162-L169

This is not the best solution as it needs to write to the filesystem. Ideally the plugin should just return a .d.ts file representing the JSON module with a custom resolve hook so that rollup-plugin-dts's transform file task won't run. However it needs to replicate some works in rollup-plugin-dts where I'm too lazy to do so.
