fix(itest): enable powertest tests in the CI

[ariasuni]

Seems like powertests aren’t checked in the CI soooooo…

• let’s enable them and see that they fail
• investigate why they changed
• fix them by generating new outputs / removing flaky tests

[ariasuni]

It fails!!

Now we can see that the differences are either due to:

• the fact that the version number of eza has been increased;
• Use clap instead of custom command line arguments parser #1447;
• fix(view)!: make --grid work when not in TTY #1556;
• or some mysterious differences in sort order that’ll I have to investigate.
