nikostr/dna-seq-deepvariant-glnexus-variant-calling: v0.3.1

This release fixes some minor bugs. It

• bumps the Snakemake version requirement to v6.5. This is due to snakedeploy not working with singularity containers in previous versions of Snakemake.
• fixes issues with QC - the MultiQC report now includes fastp output, as well as FastQC output, as intended.
• adds files necessary to generate the report.
• adds snakefmt to the tests, and removes the snakemake-github-actions dependency
