Steps to reproduce

Following the directions for true-value and false-value checkboxes, the v-model property warns of an incorrect type.

What is expected?

The true-value and false-value property type should influence the expected types of the v-model property.

What is actually happening?

The v-model property is restrict to https://github.com/vuejs/core/blob/e340add5a541df5d6563e24b11551b0d161d2f38/packages/runtime-dom/types/jsx.d.ts#L474

Any additional comments?

This was first reported at https://github.com/johnsoncodehk/volar/issues/2341. The suggested solution fixes the type error, however it then prevents utilising const toggle as a string in the script.

https://github.com/vuejs/core/blob/7d0c63ff4361e59e820441a24bf4fb2a93335a1e/packages/runtime-dom/src/directives/vModel.ts#L251

getCheckboxValue define _typeValue and _falseValue type is _trueValue?: any _falseValue?: any

https://github.com/vuejs/core/blob/c6eb3ccccee8e43e7aafcbc3c9ededecc565fdf0/packages/runtime-dom/src/patchProp.ts#L52

that mean's true-value and false-value is any type of data

https://github.com/vuejs/core/blob/7d0c63ff4361e59e820441a24bf4fb2a93335a1e/packages/runtime-dom/src/directives/vModel.ts#L159

Input v-model actual value is _modelValue, toggle's type should be the same as _modelValue type, no same as checked.

So I think this is a volar type checking problem.
