Tim Oliver dcda4e75ee Replaced FBReportMustFix with IGFailAssert (#1653)
Summary:
## Changes in this pull request

`FBReportMustFix` isn't recognized by the public version of IGListKit. It is wrapped by `IGFailAssert` to abstract error tracking between the public and private versions, and so this change was causing the GitHub repo to stop compiling.

This diff makes the appropriate change and confirms the unit tests are passing again.

### Checklist

- [x] All tests pass. Demo project builds and runs.
- [x] I added tests, an experiment, or detailed why my change isn't tested.
- [x] I added an entry to the `CHANGELOG.md` for any breaking changes, enhancements, or bug fixes.
- [x] I have reviewed the [contributing guide](https://github.com/Instagram/IGListKit/blob/main/.github/CONTRIBUTING.md)

Pull Request resolved: https://github.com/instagram/IGListKit/pull/1653

Test Plan:
Compiling again!
