Describe the bug

While voting is going on in a budget process, the option show_votes is typically disabled, and vote counts are not publically visible. The intention is that vote counts will only be displayed on the website when the results are officially announced in a later phase. However, users downloading the "open data" archive by clicking on the link in the footer receive a file that contains the current vote counts.

To Reproduce

Add a new budget component, and for some phase leave "show votes" unchecked

Click "Download Open Data files" on a public page. Unzip and open the file try.decidim.org-open-data-projects.csv. The file contains a column confirmed_votes that should not be publically visible.

Expected behavior

confirmed_votes should not appear in the open data.

Additional context

I posted a related proposal on metadecidim two months ago: Export budget votes

There I propose adding a more detailed export option in the admin dashboard, while removing vote counts from the standard export when show_votes is disabled (and thereby also removing it from the open data).

I have implemented my proposal and could open a pull request:
develop...DominikPeters:decidim:feature/budget_projects_and_votes_export

To fix the specific issue with too much data disclosure, only the mini changes from that diff for the files project_serializer.rb and project_serializer_spec.rb are needed.
