Devcontainers should include Poetry version 1.6.1 (or 1.7.1?)

The ACA-Py libraries are built with 1.6.1
https://github.com/hyperledger/aries-cloudagent-python/blob/main/poetry.lock

so probably want to stay in sync for this repo's Poetry usage in the devcontainer? Currently "POETRY_VERSION": "1.4.2"
https://github.com/hyperledger/aries-acapy-plugins/tree/main/plugin_globals/.devcontainer

Each individual plugin seems to have been generated on 1.7.1 though. But the devcontainer definitions say 1.4.2 as well

I ran the script locally that's why it's 1.7.1. Dev containers should be updated ✔️

Ok thanks. I did a PR to update them here. Found 1.4.2 references in dockerfiles too
