fix(common): allow to specify only some properties of DatePipeConfig (#51287)

PowerKiKi · atscott · commit 85843e8212e9 · 2023-10-06T12:13:13.000-07:00
The code already supports `DatePipeConfig` to have only some properties set, and not all. But the typing disallows it. This aligns the typing with the code. PR Close #51287
