chore(project): Pin poetry version to 1.8.4

[b4handjr]

Because

• Poetry introduced some breaking changes with their v2 release

This commit

• Pins all poetry installs to 1.8.4 for now.

Fixes #11998

LGTM thanks!

I'd suggest 1.8.4 for this change because we use that in all of the other Dockerfiles (except Cirrus which is on 1.6.0?), or updating those to match, but don't think that's a big deal.

We may want to consider using POETRY_VERSION env var as well in the future.

Want to file a ticket for whichever of the above you don't include here?

Good catch, ill do 1.8.4 then. Not a big difference between the two.
