RFC 5737 establishes a few IP subnets reserved for documentation-use. Since in the comments for 3317db1 it was expressed that users should simply run incus network edit incusbr0, it seems appropriate that a documentation-use range be used as the default here, since the defaults then kind-of represent a sample config which should be changed later.

It's also not the end of the world if two applications clash in the RFC5737 range, since if that happens, the user should simply change one of the applications to a subnet of their choice. The RFC5737 probably will never be a system-default subnet that could cause bad behaviour if clashed with.

Fixes #1486.

Sorry, just a moment, need to change 192.0.2.0/24 to 192.0.2.1/24.

### Release Notes

<details>
<summary>abiosoft/colima (abiosoft/colima)</summary>

### [`v0.10.0`](https://github.com/abiosoft/colima/releases/tag/v0.10.0)

[Compare Source](abiosoft/colima@v0.9.1...v0.10.0)

#### Highlights

This release introduces AI support and other updates.

##### AI is here

Colima now has AI support.

By leveraging [Krunkit](https://github.com/containers/krunkit) and [Ramalama](https://ramalama.ai/), Colima is able to provide the ideal platform to run confined, isolated and secure gpu-powered AI workloads on Apple Silicon devices.

```sh

# run a model
colima model run gemma3

# serve a model, chat interface would be availabe at localhost:8080
colima model serve gemma3

# for more
colima model --help
```

#### Other Updates

- Addition of `krunkit` virtual machine type with gpu support. `colima start --vm-type krunkit`.
- Incus instances are now reachable directly from the host if network address is enabled. `colima start --network-address`.
- Containerd runtime (with nerdctl command) now inherits `CONTAINERD_*` and `NERDCTL_*` environment variables on the host.
- Port forwarding can now be disabled by passing `--port-forwarder=none` to `colima start`.
- Volume mounts can now be disabled by passing `--mount=none` to `colima start`.
- Download mechanism has been reworked in native Go, eliminating dependency on `curl` and `shasum` on the host.
- New `after-boot` and `ready` provision modes for provision scripts.

##### Runtime version bumps

**NOTE:** container runtime versions can be updated manually by running the `colima update` command.

- Docker version updated to `v29.2.0`
- Nerdctl version updated to `v2.2.1`
- Incus version updated to `v6.21`
- K3s version defaults to `v1.35.0+k3s1`.
