Add "aria-pressed" only for toggle button and not all buttons

"Hi Bryntum Team,
We have a button added on one of our columns of the grid. When we tested it with Narrator, it read it as "Toggle Button" while it's not a toggle button. We have tried setting aria-pressed=null and it worked properly. But I think the aria-pressed attribute should not be added to the button element unless the button is configured as toggleable."

Checking MDN docs we have

Adding aria-pressed to an element with a role of button turns the button into a toggle button. The aria-pressed attribute is only relevant for toggle buttons. It represents the button's current "pressed" state.

So, it makes sense to have aria-pressed added only when it's a toggle button.
