Nanopore-conda-environment.yaml update

[tarah28]

Hello,

Thanks for creating this nextflow pipeline! I am just setting it up using conda on an Ubuntu 18.04 workstation and noticed a problem. When I install artic with conda it installs artic 1.2.1 and pyyaml 5.4.1.

But in the ncov2019-artic-nf/environments/nanopore/environment.yml it lists dependencies as artic 1.1.3 and pyyaml 5.3.1. I'm not sure what else would need to be updated in the other scripts but thought I should pass this info on. I downgraded my installs to match the .yaml file and got it to work but was wondering if this could be updated to the latest versions please?
