chore(form-core): remove unused imports (#1245)

* style(form-core): remove unused imports

Remove unused `FormAsyncValidateOrFn` and `FormValidateOrFn` imports from
`formOptions.ts`. These types were not referenced in the file, and their
removal improves code cleanliness without impacting functionality.

No functional changes.

* ci: apply automated fixes and generate docs
