Need a Home in Developer site for these from RiverscapesTools

[joewheaton]

Some content that should be referenced from https://tools.riverscapes.net, but does not belong there (belongs here) is:

• Migrate this page: https://tools.riverscapes.net/developing/
  • Migrate subpage: https://tools.riverscapes.net/developing/Release_Checklist.html
  • Migrate subpage:https://tools.riverscapes.net/developing/Docker.html

I would ask some mix of @MattReimer, @philipbaileynar, @KellyMWhitehead and @jtgilbert to confirm that the instructions and content are still accurate/relevent.

I would ask @philipbaileynar to think about where in the organization of the Developer Site this content makes sense.
