T298318: Clean up address type A/B tests should be done first before tackling this

Pull requests https://gitlab.com/fun-tech/fundraising-app-frontend/-/merge_requests/254 and https://github.com/wmde/fundraising-application/pull/2619 solve this ticket and do the cleanup for the Fundraising App.

The URL parameter for the banners will be &ast=0 for "normal" address form and &ast=1 for the "email only" address form. Pass it as an object to the formActionProps property of the DonationForm component.

@kai.nissen Is a full name and email address sufficient for SEPA and processing by VEWA? If not, you might want to test the flow of selecting email-only and then going back to the payment data - should the "Lastschrift" option be disabled or have a notification?

To get an overview of what address types are currently left

direct (ticket language)/
BasicAddressType.vue or AddressTypeBasic.vue (code language):
?ast=0

multistep_var or require_address (ticket language) /
AddressTypeNoAnon.vue or AddressTypeFullOrEmail.vue (code language):
?ast=1

the fundraising app changes for this ticket are currently deployed to
https://testing01.wikimedia.customers.manitu.net/?ast=0
https://testing01.wikimedia.customers.manitu.net/?ast=1

@CorinnaHillebrand_WMDE since it is a retest, we have to collapse the form like we did last year

@tmletzko we fixed that some minutes ago, I redeployed to testing01, you can have a look

app changes are merged are deployed to production
