Add workflow for testing with all deps (#4410)

# Add action to test with all dependencies installed PR adds a custom action for setting up poetry that allows specifying a cache key: https://github.com/actions/setup-python/issues/505#issuecomment-1273013236 This makes it possible to run 2 types of unit tests: (1) unit tests with only core dependencies (2) unit tests with extended dependencies (e.g., those that rely on an optional pdf parsing library) As part of this PR, we're moving some pdf parsing tests into the unit-tests section and making sure that these unit tests get executed when running with extended dependencies.
