* Fix some eslint complaints
* Fix some basic a11y issues in onboarding
- Missing a main element
- TODO to enable zooming
- Rename a duplicate ID attribute
I may need some context on the zooming thing, why did we decided to
disable that in the first place? It is a pretty bad a11y issue, we will
need to fix whatever that is a workaround for instead of making it
difficult for some people to use our onboarding.
