v0.69.0

## Release Notes

#### ✨ Highlights

Pixi now supports easy authentication to prefix.dev, just like GitHub CLI you can run:
```shell
pixi auth login prefix.dev
```
And it will take you to the login page of prefix.dev.

Next to that publishing a package became much easier with `--variant`, `--build-number` and more.
