Question on tox-gh-actions dependency: Is this really a runtime dependency?

[kastl-ars]

Dear maintainers,

just found hardeneks and found it interesting. While looking through the dependencies I noted that tox-gh-actions is listed as a runtime dependency:

hardeneks/pyproject.toml

Line 14 in 94f9514

tox-gh-actions = "^3.0.0"

Is this really a runtime dependency? As tox itself is listed as a test dependency, I wonder why tox-gh-actions is not in the tool.poetry.group.test.dependencies section, too.

Kind Regards,
Johannes
