Update Deps For Jan 2022

[tres]

This modification is the result of running "mix deps update --all"

We were having some issues related to the locked version in the mix lockfile, so we updated 🙌.

Additionally, we had some tests failing as they were still using Poison, so we updated those too 🙌.

Thanks!
