Update "Setting Pathway Information Free" to use a signaling pathway

[khanspers]

Current drawing paths only explain metabolic pathways, and we have some specific tasks that are relevant for other types of pathways like signaling pathways (listed below). But it would be good to expand these instructions into a full path relevant for signaling pathways, as they are a big part of WP and current instructions don't explain some aspects that are critical to this type of pathway.

Relevant tasks:

Potential target pathways (PFOCR):

Instead of adding a new track, the "Setting Pathway Information Free" track will be updated, since the "My First Metabolic Pathway" already covers metabolic pathway content.
