Needed: SARS-CoV-2 amplicon variant analysis tutorial needed

The existing [SARS-CoV-2 variant analysis] tutorial is focused on the analysis of metagenomic sequencing data. The majority of data being produced, however, uses the ARTIC amplicon protocol (for Illumina and Nanopore). The [RECoVERY](https://www.biorxiv.org/content/10.1101/2021.01.16.425365v2.full), [SANBI](https://galaxy.sanbi.ac.za/workflows/list_published?__identifer=ffcdtn4xsl) and the [Galaxy COVID-19 project](https://covid19.galaxyproject.org/artic/#analyzing-artic-data-with-galaxy) have produced workflows for SARS-CoV-2 amplicon analysis.

A new tutorial is needed walking through at least one of these workflows. It can also mention the use of Nextclade and Pangolin.

I (@pvanheus) propose to develop such a tutorial and refine it during the ASBCB Omics Codeathon: https://datascience.nih.gov/news/participant-applications-asbcb-omics-codeathon in June.

To fill out that form, enter your details, mention the Galaxy SARS-CoV-2 Amplicon tutorial and then select:
1. Would you like to pitch a project idea for the codeathon: *No*
2. Would you be interested in being a team lead for a project *No*
3. Here are some approximate project titles, please pick the top three you are interested in working on *New projects as they arise*

(this last one because our project is not on the official list (yet))
