Improve Accessibility of SideMenu Component

[blesildaramirez]

Issue Description

Currently, there's an accessibility issue with how the header elements are rendered from Primevue's PanelMenu component.
We raised an issue with the PrimeVue team regarding the aria-expanded attribute behavior in the PanelMenu component, which is currently used in our SideMenu component. The issue is about the attribute being removed when the item is collapsed, instead of being set to "false".

Action

You can find the original issue here: primefaces/primevue#6430. When this issue is resolved, we'd like to upgrade to the newer version of primevue where the fix is, and ensure that accessibility is improved on our SideMenu component.

What application are you using?
