Rfc3339DateJsonAdapter puts the wrong zone on dates like "2025-11-20"

[swankjesse]

Given a date with no time component like "2025-11-20", Moshi will use the host computer’s time zone instead of UTC.

This problem doesn’t occur if the date has a zone suffix like "2025-11-20Z".

Hi,
This looks deliberate, does this need changing? new to the repo so might be wrong please pardon my ignorance.

assertThat(adapter.fromJson("\"1970-01-01\"")).isEqualTo(newDateWithHostZone(1970, 1, 1));
