Gff release number is not a number anymore

[mpoelchau]

RefSeq has changed the way they name annotation releases (https://ncbiinsights.ncbi.nlm.nih.gov/2023/02/09/new-refseq-annot-names/). It's now a string (e.g. GCF_027563975.1-RS_2023_02) and not an integer (e.g. 100).

CWL is pretty particular about inputs - if an input only has numbers, it will complain and fail if the input type is defined as a string. I'm not sure how to update our workflow to ensure it's backwards compatible with the old release number style.
