Some ETOS Python packages not working with latest tox and setuptools

[andmat900]

Description

Some ETOS Python packages that were migrated to pyproject.toml a few months ago now aren't working with latest tox and setuptools.

Affected packages:

• etos-library
• etos-environment-provider
• etos

An attempt to run tox results in

  File "/home/user/src/etos-library/venv/lib/python3.9/site-packages/setuptools_scm/_get_version_impl.py", line 101, in _get_version
    version_string = _format_version(parsed_version)
  File "/home/user/src/etos-library/venv/lib/python3.9/site-packages/setuptools_scm/version.py", line 449, in format_version
    assert main_version is not None
AssertionError

The problem is caused by this setting in pyproject.toml, which tox does not seem to understand:

[tool.setuptools_scm]
version_scheme = "setup:version_scheme"
local_scheme = "setup:local_scheme
