review/refactor qubit mapping tutorial

[javabster]

This is a brand new tutorial currently being worked on by Haimeng from Nates team, please work with her on this issue

• [ ] decide: Haimeng finish her PR or hand over immediately to docs team?
• [ ] move source file (from above PR) to this repo
• [ ] review/refactor - needs to use vf2 layout instead of mapomatic
• [ ] review/refactor - should this be a page in the transpile section of docs instead of a tutorial?
