🚀 Feature Request: support import with type syntax (standard now)

[treeder]

Describe the solution

Workers can import JSON like this:

import Something from './file.json'

But you can't do that anywhere else.

This works in Chrome and node, etc:

import Something from './file.json'  with {type: "json"}

But does not work in workers, you get:

It would be nice to have workers support "with type" so it can be used in various places without having to change it specifically for workers.

Spec: https://github.com/tc39/proposal-import-attributes

Supported almost everywhere: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import#browser_compatibility

I just needed this to use the Fedify ActivityPub server framework on Workers. This one cannot be polyfilled as it’s a syntax feature, so I had to strip the import attributes with a post-install script.
