Accordion p-accordion toggle arrows seem reversed

[esthersoftwaredev]

Describe the bug

As I was using the accordion, placing it in a component in my v19 app, I took a look at the toggle arrows:

when collapsed they are all pointing up and the element is chevronupicon

when I toggle the arrow of course does change to the opposite and becomes a chevrondownicon

One of my apps with Angular Material UI:

So in my latest app with PrimeNG, I am rotating them like this:

It just feels more intuitive this way, to me at least.

Please let me know if it is ok to work on this and I can prepare a PR later on.
