- Adds an util `toSpliced`. We cannot used the native Javascript
`Array.prototype.toSpliced` method as Chromatic servers don't support
it.
- Makes sure Select field options have sequential positions after
removing an option (form validation schema checks that positions are
sequential and considers options invalid otherwise).
