text: Title: ignore_basepython_conflict option is not in effect in tox4
  Body: ## Issue
  
  Seems ignore_basepython_conflict option is not in effect in tox4. Setting it up to True or False doesn't change anything if envlist contains py310 but python3 points to python3.8.
  
  ## Environment
  
  Provide at least:
  
  - OS: Linux Mint 20.3, running in VirtualBox
  - `pip list` of the host Python where `tox` is installed:
