github: add surveys repository

[djacu]

Add a new surveys repository for centralizing questions used in community and other official surveys, the data acquired from the survey and the code to process survey data into meaningful visuals.

Is the data to be made public anonymized?

@pbsds
If I recall correctly, the data we collected from the NixCon NA 2024 survey was already anonymized. I have not see the raw Nix Community survey data from the past 2 years, but if it is not anonymized directly from lime survey, then it would be made so before publishing.

@fricklerhandwerk @GuillaumeDesforges since you two worked on the surveys in the past, do you see any issue with publishing the answer data if it is anonymized?

[fricklerhandwerk]

I would absolutely not publish the raw data, it's too fine-grained to be meaningfully anonymous. We didn't do it in the past either. But having a normalized public representation of the aggregate results would be super valuable to analyze trends.

[djacu]

Ok no raw data then. Only normalized data if possible.
