Allow translations for time slider `aria-valuetext`

[joao-almancio]

Related Problem:

I'm not able to provide translations for the words out of, hours, min and sec for time slider in default layout's aria-valuetext property.

• timer-slider.ts on the line 241
• time.ts on the line 94

Describe:

For a multilanguage website I need to provide accessible and translated content for user.

Alternatives:

I would consider the usage of a function to compute the property aria-valuetext

const getARIAValueText = getUserCustomARIAValueText 
  ? getUserCustomARIAValueText({currentTime: time, duration: duration() }) 
  : `${formatSpokenTime(time)} out of ${formatSpokenTime(duration())}`

This way, dev will have greater flexibility to deal with other languages. Of course people could mess putting some computation heavy function but it's just an idea.
