fix(VMenu): remove redundant aria-owns breaking VoiceOver on Safari

[waterWang]

Fixes #22540

Problem

The aria-owns attribute was added to the VMenu activator in commit 975a18c (PR #22240) alongside the existing aria-controls. On Safari + VoiceOver, this causes the menu item labels to not be read — only "menu item" is announced without the label text.

Root Cause

aria-owns on Safari + VoiceOver interferes with the reading of the menu item labels. The reporter confirmed that removing aria-owns from the DOM resolves the issue.

Fix

Remove the redundant aria-owns attribute from the VMenu activator props. The aria-controls attribute already establishes the relationship between the activator and the menu content, making aria-owns unnecessary and duplicative.

The original issue (#22226) that prompted adding aria-owns is still addressed by the aria-controls attribute, which is the correct ARIA attribute for indicating a controlling relationship between elements.

Testing

• VoiceOver on Safari: menu items now read their labels correctly
• Chrome: unaffected (works with or without aria-owns)
• No change to the valid-file upload path
