Ensure dependencies are printed to stdout in parallel

[ziima]

Issue

--list-dependencies in parallel runs makes dependencies printed, but whole standard output is redirected to logs. This causes the argument somewhat unusable. The dependency output should be printed to standard output.

Minimal example

tox run-parallel --list-dependencies -e quality,py312
py312: OK ✔ in 29.52 seconds
  quality: OK (32.98=setup[32.40]+cmd[0.01,0.35,0.21] seconds)
  py312: OK (29.52=setup[24.55]+cmd[4.97] seconds)
  congratulations :) (33.03 seconds)
