Fixup: Add date annotations for rare genotypes

Six of the samples that are force-included in the Nextclade dataset tree have empty collection date fields in the metadata output from NCBI Datasets. This results in the samples being removed downstream by the TreeTime clock filter. This commit adds collection dates (which were manually extracted from the strain names in the NCBI metadata) for these samples so that they will be included in the Nextclade dataset tree.
