Type of "year" slot is incorrect

[Tsuyoshi84]

Describe the bug
The type definition of year slot seems to be incorrect.

The document says that value will be passed from the year slot.

I also confirmed that I can use value to show the year.
However, according to the type definition, I'm supposed to use year instead of value.

vue-datepicker/index.d.ts

Line 404 in 7eceb72

year(props: { year: number }): any;

Because of that, if I follow the document instruction, I get a type error.

To Reproduce
N/A

Expected behavior

I assume the type definition needs to be like this:

    year(props: { text: string; value: number }): any;
