support import types for pure JS files

[obiot]

using this fix issues with generated TypeScript definition where defined @types in JSDoc are not being found :

for example

/** 
 * @type {import('./../physics/body.js').Body}
 */

But as of now, this generates an unknown value with webdoc:

body
body: unknown

unknown
