ci: ignore bundle size reporter failures (#32490)

Summary:
CircleCI stopped populating `CIRCLE_PULL_REQUEST` without providing an
alternative, so now it's impossible to get the PR number unless it comes
from a forked repo.

## Changelog

[Internal] [Fixed] - ignore bundle size reporter failures

Pull Request resolved: https://github.com/facebook/react-native/pull/32490

Test Plan: CI should ignore bundle size reporter failures.
