retain build compat with py3.6

[briantist]

CI is failing now after merging #1015 , only on python 3.6, even though CI was passing with the PR contents. I believe this might have something to do with changes made in #1016 which was merged shortly before. The CI on that one was also passing, but the sdsist installation tests didn't exist then, so I think this failure is a combination of the issues.

Failure:

• https://github.com/hvac/hvac/actions/runs/5393829500/jobs/9794479959

The error looks like what's described here:

• Dependency group feature breaks managing environment support for python 3.5 & 3.6 python-poetry/poetry#7477

that despite poetry supporting python 3.6, poetry-core had already dropped it. I don't really see how the changes in #1016 affected that, since it didn't change the poetry core version, but I'm attempting to fix it for this one release that we're doing before we drop Python 3.6 in 2.0 soon.

it looks like my suggested fix was the exact wrong thing to do; I guess it forced using the incompatible core version to all version of python... I may try to revert the conversion to the group syntax for poetry and then we'll bring it back after 3.6 is dropped..
