Add donors scraping in GH actions

[Xpirix]

Fix for #426

Summary:

• Get the script stripe_donor_logger.cgi and its dependencies from the old repo
• Update and test them locally
• It should be set up with nginx on the server side and ensure that the webhook link on stripe points to it. Please find the proposed change for that at: https://github.com/qgis/QGIS-Sysadmin-Documentation/pull/66

The cgi script will:

• Be called whenever a donation has been made on stripe
• Receive the donation information
• Add the donor name to the file donors.json
• Pull from the origin repo, commit and push this change to the main branch

For this change, I kept the process of manual deployment for now.

Let me chat with @andreasneumann a bit about this - I am not too mad about turning our static site back into a dynamic site. Maybe we can implement this on a GH action rather or on a server that is not exposed to the internet....

Can we not do this as a gh action rather to do the scraping and update the deployment bundle (when we have teh site as a nixos package) e.g. once a day?

I think we need to find another way e.g. as a gh action. I don't want to run code and cgi scripts on our server.

Latest Updates according to previous comments

• Added a script update_donors.py: it fetches new donors from Stripe API and updates the donors list accordingly.
• Run update_donors.py in GitHub actions with the update-donors.yml workflow
• The script requires the variable STRIPE_API_KEY from the secrets
• The schedule is similar to the update feed workflow, i.e each day at noon (UTC)
• Running the workflow for the first time will create a file at scripts/latest_donation.txt to store the timestamp of the latest donation. In the future, it will be used to fetch new donors. So that you know, running this workflow for the first time might take a while (depending on the number of existing donors) since it doesn't have this reference yet and will retrieve all donors from Stripe.
