Description

This PR removes @reach/auto-id in favor of React.useId in react-form-fields. The remaining packages using @reach/auto-id are no longer being maintained.

As a part of this PR, @types/react was updated to v18, and react-docs-page was adjusted to account for the breaking changes (namely the deprecation of the FunctionalComponent utility type).
