chore(main): release v1.35.0

[hcloud-bot]

Zone Label

The datacenter property was removed from the Server object (see changelog. For backwards compatibility, we statically compute the datacenter from the location to fill the topology.kubernetes.io/zone and failure-domain.beta.kubernetes.io/zone labels. In the next major release we will stop setting these values. To stop setting these values now, you can set the environment variable HCLOUD_INSTANCES_ZONE_LABEL_ENABLED=false. See here for more details.

### Zone Label

The `datacenter` property was removed from the Server object (see [changelog](https://docs.hetzner.cloud/changelog#2026-07-01-removing-datacenters). For backwards compatibility, we statically compute the datacenter from the location to fill the `topology.kubernetes.io/zone` and `failure-domain.beta.kubernetes.io/zone` labels. In the next major release we will stop setting these values. To stop setting these values now, you can set the environment variable `HCLOUD_INSTANCES_ZONE_LABEL_ENABLED=false`. See [here](docs/guides/zone-label.md) for more details.

Suffix / End

This will be added to the end of the release notes.
