[Feature Request] Allow `cancel-button-text` and `confirm-button-text` etc to be false about vant

[chenjiahan]

We can add new show-confirm-button and show-cancel-button props and keep confirm-button-text as string type

[chenjiahan]

Yes, this is also a feasible solution, and I remain open to it.

Current solution is to override confirm slot but it is requires more code.

[mahnunchik]

vant/packages/vant/src/picker/PickerToolbar.tsx

Lines 55 to 63 in dbf8027

	const text = props.confirmButtonText || t('confirm');
	return (
	<button
	type="button"
	class={[bem('confirm'), HAPTICS_FEEDBACK]}
	onClick={onConfirm}
	>
	{slots.confirm ? slots.confirm() : text}
	</button>

@chenjiahan Yes, it is one of possible solutions.

But my point of view, that show-* props for all *-text texts may encrise amount of props almost twice.

Another option is to fix handling empty strings here

vant/packages/vant/src/picker/PickerToolbar.tsx

Line 55 in dbf8027

const text = props.confirmButtonText || t('confirm');

to be able to render empty sting by :confirm-button-text="" as expected.

I mean something like the following:

const text = props.confirmButtonText !== undefined ?  props.confirmButtonText : t('confirm');
