Withdraw HK.10 for now, as it turns out it's only 5 sequences from 2 …

…Chinese provinces, rather than 15 global

When designating, I missed that this lineage had the C19983T reverted for most sequences except for 5
Had I known this, I would not have designated, hence retracting.
In case this lineage grows to at least 20 sequences this lineage can be redesignated.
