Maybe a Bug?

When user pass .000Z milliseconds in GET /search request, the ms part gets removed

This is all coming down to https://github.com/stac-utils/stac-fastapi/blob/6d655253182a031c1c0eb05268e7bb5df4a46726/stac_fastapi/types/stac_fastapi/types/rfc3339.py#L51C5-L92

rfc3339_str_to_datetime("2000-01-01T01:01:01.000Z")
>>> datetime.datetime(2000, 1, 1, 1, 1, 1, tzinfo=datetime.timezone.utc)

☝️ when we convert the datetime string to datetime, then the datetime has microseconds set to 0

Then when we convert the datetime back to string (in stac-fastapi-pgstac) we use .isoformat() method

datetime.datetime(2000, 1, 1, 1, 1, 1, 0, tzinfo=datetime.timezone.utc).isoformat().replace("+00:00", "Z")
>>> '2000-01-01T01:01:01Z'


datetime.datetime(2000, 1, 1, 1, 1, 1, 1, tzinfo=datetime.timezone.utc).isoformat().replace("+00:00", "Z")
>>> '2000-01-01T01:01:01.000001Z'
