[BUG] Testing with jest/vitest (scrollIntoView is not available)

[cguedes]

Describe the bug
When using kmenu in unit tests, with Testing Library and jest/vitest, the tests fail because scrollIntoView is not available.
I've identified that the cause is that the function isn't implemented by jsdom.

To Reproduce
Steps to reproduce the behavior:

1. Create a project with kmenu
2. Create a unit test using testing library
3. Create a test that renders the kmenu
4. Ensure that the kmenu renders (open the menu by default for example)
5. See error "scrollIntoView is not available"

Expected behavior
The component should render it's content inside the test runner.

Additional context
This can be fixed by adding the missing function without any implementation.

window.HTMLElement.prototype.scrollIntoView = () => { };

Hey, @cguedes, I'm unsure on how I should go about helping you here? You gave me all the details I asked for but I'm unsure if I fully understand how this can be fixed.

Hi. That's a good point. Maybe you can add some init tests to identify the best way of fixing this. Additionally you can have a note in README.md
