Support role="slider"

I understand that the author doesn't work actively on the project, so this issue is just a reminder that I did bump into the lack of it.

Otherwise a fantastic extension, and thanks so much for it.

Hi @sarimarton,

Thank you so much for the kind words! Recently I've dropped my full time job to pursue a dream of being independent developer working on my own projects. To make it sustainable I have to be very careful on what I spend my time on and unfortunately ARIA DevTools currently doesn't bring any revenue to me.

I would love to work further on ARIA DevTools if I find a sponsor of the project (I don't want to make the extension paid). I will add a note about this to the project README and perhaps someday, someone will be open to sponsor the development :)

Cheers,
Mateusz
