Refine short-title of WebAPI event pages

### MDN URL

https://developer.mozilla.org/en-US/docs/Web/API/Element/input_event

### What specific section or headline is this issue about?

_No response_

### What information was incorrect, unhelpful, or incomplete?

The [Element: input event](https://developer.mozilla.org/en-US/docs/Web/API/Element/input_event) page has the following breadcrumbs:

- [Web](https://developer.mozilla.org/en-US/docs/Web)
- [Web APIs](https://developer.mozilla.org/en-US/docs/Web/API)
- [Element](https://developer.mozilla.org/en-US/docs/Web/API/Element)
- [input](https://developer.mozilla.org/en-US/docs/Web/API/Element/input_event)

This confused me a bit, because `input` is also [an HTML _element_](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/input), which has the following breadcrumbs:

- [Web](https://developer.mozilla.org/en-US/docs/Web)
- [HTML](https://developer.mozilla.org/en-US/docs/Web/HTML)
- [Reference](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference)
- [Elements](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements)
- [\](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/input)

### What did you expect to see?

I would expect the breadcrumb leaf for the event page to has an indicator, such as "input event" or "input (event)".

### Do you have any supporting links, references, or citations?

_No response_

### Do you have anything more you want to share?
