[Bug]: discrepancy between doc and ts typings for the property controlInput

[R1Daneel]

Bug description

The documentation states that null is a valid value for the controlInput setting:

description	Type	Default
Supply a custom element. Supplying a null value will disable the default functionality.	NodeDefinition|null	<input...>

However, the TypeScript typings specify that controlInput can only be of type string |HTMLInputElement, with no mention of null: https://github.com/orchidjs/tom-select/blob/master/src/types/settings.ts#L62

Expected behavior

Either:
1. The documentation should be corrected if null is not actually a valid value.
2. The TypeScript definition should be updated to include null if it is indeed a valid option.

Could you confirm the intended behavior so that we can align the documentation and typings accordingly?
