fix(ui5-date*): remove aria-pressed from time selection clocks

[hinzzx]

Problem

The ui5-toggle-spin-button component (used in ui5-time-picker, ui5-datetime-picker, ui5-date-picker, ui5-date-range-picker) has role="spinbutton" but includes aria-pressed attribute, which is not a supported attribute for the spinbutton role per WAI-ARIA 1.2 spec.

1. Invalid ARIA attribute — aria-pressed is not in the list of supported states/properties for spinbutton role

Solution

Removing unsupported aria-pressed attribute.

What This Fixes

• ✅ ARIA 1.2 — spinbutton role no longer has unsupported aria-pressed attribute
• ✅ AXE/AccessContinuum — invalid ARIA attribute violation resolved
• ✅ No visual or functional changes
