Poetry 1.2 support #1241

ref: 8c692b3

CodeQL will not work with projects that use the new Poetry 1.2 features, such as dependency-groups:

As the dev-dependencies is now deprecated, projects should migrate to the new group syntax as soon as possible. Keep in mind that the group syntax is a new feature of Poetry 1.2, and your project will not be buildable with Poetry 1.1 after migrating.

CodeQL error:

Warning: An error occurred while trying to automatically install Python dependencies: Error: The process '/usr/bin/python3' failed with exit code 1
