Fix: Prevent undefined properties at the root level

Fixes: rjsf-team#3424 by preventing the inclusion of undefined properties at the root level - Updated `@rjsf/utils`, making `computeDefaults` helper in `getDefaultFormState()` to skip adding undefined values when `excludeObjectChildren` is set. - This basically supports adding an empty object - Updated the tests accordingly - Updated the `CHANGELOG.md` accordingly - Also added information the changelog for PR rjsf-team#3202
