Use Poetry 1.8.5 for Python 3.8

[edgarrmondragon]

What are you trying to accomplish?

Poetry 2.0 dropped support for Python 3.8, so this ensures a version Poetry can be installed until support for Python 3.8 is dropped.

• Bump poetry from 1.8.5 to 2.0.0 in /python/helpers in the poetry group #11227
• Deprecate / remove support for Python 3.8 #10817

Anything you want to highlight for special attention from reviewers?

How will you know you've accomplished your goal?

Thanks for putting this up.

However, given that 3.8 was EOL'd in October, and we've already started marking it as deprecated (#11166) we may be able to bypass this completely and simply drop 3.8 within the next few weeks:

• Deprecate / remove support for Python 3.8 #10817

@amazimbe is working on that and can speak to the timeline more.

This effectively bumps to Poetry 2.0.0... that's a much bigger change than just pinning poetry 1.8.5

I would not be surprised if this part of this change introduces a bunch of breakage that needs fixing...

Thanks for the feedback @jeffwidman! I wasn't aware the 3.8 deprecation was so close to being dropped. I agree that there will be breaking changes when bumping to Poetry 2.0, but I unfortunately can't work on fixing those at the moment.
