Errors with `bobtemplates.plone` with version `>=6.0`

Versions 6.0, 6.1, and 6.2 of bobtemplates.plone raise following errors (both in Linux and Windows):

ERROR: tox config file (either pyproject.toml, tox.ini, setup.cfg) not found
Error on isort-apply:
ERROR: tox config file (either pyproject.toml, tox.ini, setup.cfg) not found
Error on black-enforce:

With older versions 6.0bx or <=5.22 I didn't get any errors.

Older versions generated/copied a tox.ini file versions >=6.0 seems not to generate a tox.ini.
