Details

Import json is transformed to js, but the import statement import attributes (with { type: 'json' }) are not removed.

import enUS from './en-US/translation.json' with { type: 'json' }; becoming import translation from './en-US/translation.js' with { type: 'json' };

Reproduce Steps

Import a json file, e.g. import enUS from './en-US/translation.json' with { type: 'json' };. Build the library and see it being transformed into import translation from './en-US/translation.js' with { type: 'json' };, which is invalid
