Snapcraft tries to run chisel and fails

[Isaac True]

If the user makes a typo in stage-packages and forgets the $ like so:

    stage-packages:
     - package:{CRAFT_TARGET_ARCH}

Snapcraft for some reason then tries to run chisel, which does not exist in the snap and fails with the following message:

    chisel: No such file or directory

This should probably be a syntax error in this case, rather than being interpreted by Snapcraft as something to do with chisel.

Thanks for this bug report! I'm able to reproduce the same issue for core22 snaps.

Snapcraft and craft-parts interpret the underscores as chisel packages and chisel is not installed in the build-environment.

I agree that error handling and user experience could be improved.
