Fix console entry point for purldb CLI #622

The console_scripts entry point in setup.cfg incorrectly referenced
"purldb:command_line". There is no top-level purldb module in the
repository, which caused the generated CLI wrapper to fail with:

    ModuleNotFoundError: No module named 'purldb'

The command_line function is defined in purldb_project, so the
entry point must reference "purldb_project:command_line".

This restores the functionality of the `purldb` CLI command when
running inside Docker as documented in the installation guide.
