Revert "add python-tasks to examples pixi environment"

Reverts #6991

pixi run -e examples py-build will NOT do what you want.

Look at the implementation. It runs:

py-build = "pixi run -e py py-build-common"

So it will override your attempt to set the environment by running with a different environment.

This is the entire reason py-build-examples exists.

ah.
But there's a comment in that pixi.toml file that says you're supposed to run pixi run py-build to run examples, that needs to be fixed

@Wumpf ok, I'm not seeing anymore obviously wrong docs.
