fix: ActionBar overflow menu not closing on select

[francinelucca]

Closes https://github.com/github/primer/issues/6382

Storybook improvements:

• Modified the Task List icon button in ActionBar.stories.tsx to include an onClick handler that triggers an alert, making the story interactive and easier to test.

Changelog

Changed

• Use onSelect for ActionBar's ActionMenu items instead of onClick so that the correct events bubble up and hide the menu upon selection.

Pull request overview

This PR fixes a bug where the ActionBar's overflow menu (the "More items" kebab menu) does not close when an item is selected. The fix changes from using onClick to onSelect for ActionList.Item components within the overflow menu, which ensures proper event bubbling that triggers the menu's close behavior.

Changes:

• Changed ActionList.Item event handler from onClick to onSelect in overflow menu items
• Removed the eslint-disable comment for primer-react/prefer-action-list-item-onselect rule
• Added an onClick handler demo in the Default story to verify onClick functionality still works
