[dev-overlay] fix: proceed to get runtime error when fails to fetch original stack frames (#75743)
### Why?
When fetch fails to get the original stack frames, the process to get the Runtime Errors fails.
The fetch will likely fail on Storybook stories.

### How?
Correctly reject when request fails so that it may be caught at `_getOriginalStackFrame()` and return the stack frame.
