support for Chimera Linux

I was trying to install k0s through k0sctl on [Chimera Linux](https://chimera-linux.org) and I got this error:

```

```

I'm not sure why but it seems that support for each distribution needs to be added manually for k0sctl to run. Not sure if `k0s` has any similar limitation.

The issue provides no file, test, or entry-point names. Start by tracing k0sctl's operating-system detection and os-release version-resolution path using the reported Chimera Linux output; done means the tool can identify Chimera Linux and proceed past the current unsupported or invalid os-release errors.
