bug: adapt runs directive to new Vib syntax

[kbdharun]

The syntax of directives like runs, entrypoint. copy and adds have changed in the recent release. At least for runs, we need to update it here to use:

runs:
   commands:
        - some-command

So that the statistics are shown properly without NaN.

For information, checkout https://docs.vanillaos.org/vib/en/recipe-structure.

Seems to be fixed now, so closing this issue. Nope, it only supports the old Vib syntax.
