Add Python 3.10 to tests

[d33bs]

Description

Through a comment in #8 (comment) I noticed there is not yet testing for Python 3.10, which could be cause for incompatibilities or errors. This PR adds Python 3.10 to Dagger and the associated automated Github Action tests for this repo.

While working on this I also found that other dependencies needed to be updated, notably Poetry 1.2 -> 1.3, along with various packages. I took a moment to address this to avoid some upstream issues as well.
