Subject: [PATCH] hetzner: use different locations for arm64/amd64

Hetzner is having some capacity issues[^1]:
- amd64: CPX plans (CPX11 to CPX51) - Falkenstein (FSN) and Nuremberg (NBG)
- arm64: CAX plans (CAX11 to CAX41) - Helsinki (HEL) and Nuremberg (NBG)

Let's switch the location:
* Helsinki (hel1) for amd64
* Keep Falkenstein (fsn1) for arm64
