v6.3.0

A big thanks to the 11 contributors who made this release possible. Here are some highlights ✨:

• Fix invalid HTML structure in the Accordion component (#44408) @ZeeshanTamboli
  The HTML elements of the Accordion summary have been updated:
  • the root element is now button (previously div).
  • summary content and the icon wrapper are now span (previously div).
    This will only impact you if you used the HTML element as selectors in your styles.
