Dayjs.min behavior with single argument

[joyhchen]

Describe the bug

Take this example to illustrate why I might end up calling with a single arg:

const list = myApiResponse.data;
const minCreatedDate = dayjs.min(dayjs.utc(createdDate), ...list.map((item) => item.createdDate))

When list is empty, dayjs.min returns null.

However, if you instead pass these args as a list to dayjs, we get the expected result:

const minCreatedDate = dayjs.min([
     dayjs.utc(createdDate),
    ...list.map((item) => item.createdDate
])

^ this returns the createdDate as expected

Expected behavior

When dayjs.min() is passed a single argument, it should still return a result if the argument is a valid date.
