Bug report

Current Behavior

I use the latest formik release with React v19, specifically "@types/react": "^19.0.1" and I get 4 errors like:

node_modules/formik/dist/types.d.ts:209:109 - error TS2503: Cannot find namespace 'JSX'.

209 export type GenericFieldHTMLAttributes = JSX.IntrinsicElements['input'] | JSX.IntrinsicElements['select'] | JSX.IntrinsicElements['textarea'];

Expected behavior

No type errors.

Suggested solution(s)

s/JSX/React.JSX

Additional context

It's only about typings anyway. In @react/types, this was backported also to the v16 series, so the proposed change doesn't require React v19 to work.
