don't block pixi commands on none linux platforms because of tutorials

[ReimarBauer]

Purpose of PR?:

Fixes #2658

when we only remove osx-arm64 from tutorials these machiches use automatically rosetta and available packages for osx.

This does not mean that the tutorials now can become created on osx-arm64 or windows but all other pixi commands like pixi lock, pixi update did not fail because of the tutorial definition.
Without that change the tutorials problems on osx or windows can't become debugged.
When we want to limit the tutorials to linux we should in a further step add a check of the platform there.

Are we planning to support the tutorials on Windows and macOS? If yes this change makes sense, but is there an issue for it already?

Irrespective of that, the underlying issue seems to be a pixi bug and deserves a report upstream: it should be possible to run pixi update on macOS even if the specified platform is Linux only. Doing an update on Linux for a Windows only project works fine for example, and it should for any combination of platforms.

ah ok, I was not aware on that.

initially it was partly, I focused for the refactoring on linux first. It was just difficult without having these platforms to understand the differences in the window managers, etc.
