rc-collapse not accessible

[mellis481]

@2betop rc-collapse's collapse/expand functionality only works on the ENTER key keyboard press. To be accessible, it must work with SPACEBAR or else it breaks WCAG 2.4.7 Focus Visible and possibly WCAG 2.1.1 keyboard.

You can see in the WCAG examples, the collapsible elements work with SPACEBAR. Can rc-collapse be updated to work with SPACEBAR?
