Improve flow of the lesson in sections 4 and 5

[anenadic]

A couple of issues:

• do we need to fork the software repo - are we looking at past commits prior to forking at all?
• we talk about releasing the project in section 4, fixing the documentation and readme and then we ask people in section 5 to open issues to fix these exact things
• Exercise /52-assessing-software-suitability-improvement/index.html#exercise-conduct-assessment-on-third-party-software does not make much sense as the code is not developed enough and also all repos are the same
• not sure that comments "### MODIFIED START ###" in code in episode https://carpentries-incubator.github.io/python-intermediate-development/36-architecture-revisited/index.html#adding-a-new-view mean

A better flow could be:

Section 4: Managing a Collaborative Software Project

• Developing Software In a Team: Code Review
• Improving Software Over Its Lifetime
  • Issues reporting and tracking
  • Software Improvement Through Feedback
• Managing a Collaborative Software Project

Section 5: Releasing and Reusing Software

• Preparing Software for Reuse and Release
  • Issue prioritisation
  • Planning sprinting and release cycles
• Packaging Code for Release and Distribution
