fix: Update accessibilityValue handling in ProgressBar to also use the animatedValue

[KevinvdBurg]

Set the accessibilityValue if animatedValue is set.

Motivation

We noticed that the accessibilityValue is probably not set when only setting the animatedValue. Because the progress and animatedValue should not be used in parallel, we can see here that animatedValue is ignored by the accessibilityValue.

    accessibilityValue={
      indeterminate
        ? {}
        : { min: 0, max: 100, now: Math.round(progress * 100) }
    }

Test plan

I added tests to check the accessibilitValue of the ProgressBar.
