Allow aria-valuetext for elements with role="slider"

[mhkeller]

Describe the bug

I have a brushable chart and the brush has a role of "slider". The Svelte compiler is telling me that I also need an aria-valuenow prop, which has to be a number. The value of brush is a range and can't be expressed as a number and so I am setting aria-valuetext. If I'm understanding the aria rules right, this seems like an acceptable setup but the compiler still issues a warning.
