Do not check limactl list exit code

Starting from lima v0.22.0 (I guess) `limactl ls <vm>` returns 1, when
the <vm> doesn't exist. That breaks many plans because list and status
tasks fails instead of returning empty result.

This commit removes the `limactl list` return code check. Maybe later
we can improve it.

Fixes #31
