Possible Update of Poetry

The poetry team released 2.0 on 1/5/2025, which included the dependency and default support for poetry export. This looks to have broken some of commands in the pipeline (see failed job).

nox > Running session pre-commit
nox > Creating virtual environment (virtualenv) using python3.11 in .nox/pre-commit
nox > poetry --version --no-ansi
nox > poetry export --format=requirements.txt --with=dev --without-hashes
The command "export" does not exist.

Given that we are going to have a discussion with the IIDD team about their approach to building pygeoapi, including the possible removal of poetry as a dependency, I just downgraded the container to version 1.*. I'm opening this issue to note that if we do continue with the poetry dependency, we should consider updating to version 2 and installing the export plugin.
