fix: ensure the #CHROM is not quoted

[project-defiant]

✨ Context

The output from convertToVcf step uses the csv writer which can not write the #CHROM column correctly to the output csv file, as writer quotes the column, so the result is "#CRHOM". This PR resolves this in a temporary solution, by removing the hash, that will be readded before the vep command is executed in the orchestration.
