fix: React onChange/onInput events not triggering on input type="file" file upload

[ybentz]

Fixes #380.

What:
This PR fixes a bug in the .upload() function that's very similar to #370. The cause of the bug and the fix are basically the same.

Why:
In React, starting with user-event v12 the onChange and onInput callbacks stopped working for <input type="file" />.

How:
Very similar to #370:

• Input event: passing the bubbles: true option to the event's options.
• Change event: Use fireEvent.change instead of fireEvent(input, createEvent('change', ....

Checklist:

• Documentation N/A
• Tests
• Typings N/A
• Ready to be merged

Notes:
As I mentioned in the related issue, we should probably check the rest of the changes in case some other similar functionality broke with the recent changes.
