Description

Can we have a common validation that every field validates with. This should work even in case of nested objects.

Eg: Object is as follows: { field1: "", field2: { field2A: [] field2B: "" }, field3: {[ field3Ai: [] field3Bi: "" ], [ field3Aii: [] field3Bii: "" ]} }

Research direction
Start by reviewing Formik's validation flow in the source code, particularly how `handleValidation` processes nested field paths. Look for existing utilities or discussions in the repository about applying a common validator to all fields. Since the issue is vague, consider asking for clarification on what kind of validation (e.g., type checking, required fields) and whether it should override per field validators. Check linked issues or comments for any prior work.
