This commit upgrades the dbt dependencies which were causing the project
to break on DuckDB

This commit upgrades the project's dependency manager to Poetry instead
of just pip. This is mainly to use Poetry's dependency resolver which is
much superior.

This commit updates the pre-commit configs to make them up to date with
the new dependencies. It also removes some random JS stuff that was
around.

This commit removes devcontainers since it was broken anyways.
