Make the surveys structure part of the repository

I think that by making the survey structure part of the repository we get multiple benefits like:

• Allow the community to contribute and discuss about the structure and the questions of the survey using PRs
• Easily replicate the survey for future years without depending on the owner of the google form
• Allow other communities from other countries to replicate the survey
• Easily fix typos
• Even comment the structure of the survey to communicate the intention of each question so that people that make analysis of the data can have a better understanding of the results

Also, using google appscript we can add validations and interactivity in case it's needed
