make use of locked markers in lock file version 2.1 and thereby avoid dependency walk failed

[radoering]

Resolves: #176
Resolves: #183
Requires: python-poetry/poetry#9427

With python-poetry/poetry#9427 we can fix dependency walk failed once and for all. The dependency walker becomes as simple as iterating over a flat list and doing some simple marker operations. There is no complicated erroneous logic anymore because the resulting markers for each locked package can be read from the lock file.

I adapted all tests so they are run with an old lock file without markers and with a new lock file with markers and added a test (at the end) that raises dependency walk failed for an old lock file and succeeds for a new lock file.

This does resolve the long-standing issue with urllib3 for us: https://github.com/meltano/sdk/actions/runs/9358298538/job/25759841162.

Very interested, we have been having issues with urllib3 as well

It requires a Poetry release that includes python-poetry/poetry#9427. That will be python-poetry/poetry#9448.
