Add Touchpoints survey to dev docs.

Jira ticket: LG-15323

[h-m-m]

I think this is a legit problem

I read this as: "the survey link obscures the return-to-top link at smaller widths"

Selector: ".return-to-top-button.desktop\\:display-none"

@rahul-kamarouthu — Is there an option in Touchpoints to adjust the location of the link at the bottom of the page? If we could move it to the left 4 rem or 32 px, that might fix the problem
