Module docs intro paragraph is out of date

[boulund]

The introductory paragraph in the Module section of the docs reads:

StaG-mwc is a workflow framework that connects several other tools. The basic assumption is that all analyses start with a quality control of the sequencing reads (using FastQC), followed by host sequence removal (using BBMap). This section of the documentation aims to describe useful details about the separate tools that are used in StaG-mwc.

It is out of date. The references/links should be changed to fastp and kraken2, respectively.
