[doc] Issue in "SUSE Edge Documentation" - Request for changing the side menu ordering

[peteingithub]

Topic order in the side menu is a bit "un-natural" with Product Documentation being lager that Day 2 Operations and others.

How about:
Quick Starts
Components
How-To Guides
Product Documentation (or even earlier/beginning)
Day 2 Operations
Tips and Tricks
Third-Party Integration
Appendix

@timirnich and @joesusecom We may need to revisit this issue on restructuring. Let me know if any decision was taken while I was away :)
