yocto-project-qs: Created two sub-sections for the "Build" section.
Fixes [YOCTO #10462]
The section that shows how to build images had two examples all
within the same section. It was suggested to place these examples
in their own sub-sections. Good suggestion. I broke them out into
sub-sections titled appropriately.
