[Documentation]: General improvements for documentation

[ehennestad]

What would you like changed or added to the documentation and why?

• Reading NWB Files and Writing NWB Files sections are partly conceptual, partly how-to.
• Revisit dataset configuration profiles - currently there are three different profiles, this should be simplified, potentially using presenting a single profile

Do you have any interest in helping write or edit the documentation?

Yes.
