Summary: Changelog: [iOS][Added] - `getRectWithAttributedString()` aims to get the rect of the fragment with embedded link, which is necessary when building the `accessibilityElement`. In this function, we first enumerate attributedString to find the range of fragments whose `accessibilityRole` is @"link". Then we calculate the rect of the fragment and send to the block and we would define what to do in the block in `RCTParagraphComponentAccessibilityProvider`.
