fix: Update types.ts to comply with TS isolatedModules

[asbermudez]

With the current export the module can produce a runtime error as we're trying to export types as if they were actual runtime elements. For this reason Typescript warns about it if the isolatedModules property is set.

https://www.typescriptlang.org/tsconfig#isolatedModules

Here an example of the current error using latest version of Nuxt (3.7.0)

Hello @asbermudez, thank you for this!

Thanks again for this. I see that you have changed the exports to per-line exports. End-of-file exports seem easier to scan and maintain.

If you are open to it, can we revert to

export type {
// ...
}

@ijkml changed ;)
