Automatically move donation.purpose to donation.usage

[maurerle]

If a community has donation.purpose set, it is marked as invalid (which was valid some time)

The generator should update that field to "usage" just as it updates the geodata field.

If this is a first draft of a PR to fix this, it might help to format this accordingly?
Where should this be added?

These autogenerated comments in a different coding language, completely unrelated to the existing project do not help.
Instead they create noise.
I reported this as spam, as it is quite likely that this account files a lot of auto generated comments that way.

@maurerle, is this issue still open?

[maurerle]

@TejasNangru - yes I think so. You can check on the deployment at: https://freifunk.net/api-generator/

@maurerle, on https://freifunk.net/api-generator/ ,it shows only the 'usage' field under the 'donations',

and also i am not able to manually add 'purpose' in JSON to check what the output comes.
