Regex used to convert oninput to oninputcapture is too broad

Describe the bug
The change in #3562 was intended to convert oninput to oninputCapture. However, because it is using /^oninput/, it actually ends up converting oninput* to oninputCapture. This breaks functionality for custom elements that might be exposing CustomEvents that happen to start with "input". i.e.

<my-custom-element oninputAction={...}/>

used to call addEventListener('inputAction', ...), but will now add a capture listener for the 'input' event.

To Reproduce

See above.

Expected behavior

Think #3573 is all that's needed.
