Documentation update: Running the rnaseq pipeline on prokaryotic samples

[MatthiasZepper]

Description of feature

The documentation of the rnaseq pipeline that refers to running the pipeline on prokaryotic samples is unfortunately completely outdated. It specifies the required settings for featureCounts, even though that tool has been superseded by salmon for transcript quantification about 10 pipeline releases ago!

On Slack, Marine Cambon has already kindly written up what is needed to run the more recent versions of the pipeline successfully with prokaryotic RNA-seq. However, somebody needs to update the pipeline documentation accordingly. Since this requires only Markdown edits, I think it is a suitable task for the Hackathon?

For some general recommendations on how to write good technical documentation, see the website of the Diátaxis framework.
