[BUG] target-path config in dbt_project.yaml is deprecated

[famazak]

dbt has deprecated the target-path configuration option in dbt_project.yaml in favor of a runtime configuration/environment variable (see dbt-labs/dbt-core#6882) for more detail. The target-path option will be removed in a future dbt version.

When running a dbt project with target-path removed from dbt_project.yaml, the re_data overview command fails with a KeyError from the below line.

re-data/re_data/command_line.py

Line 57 in e5db6c1

project_dict['target-path']

To support dbt's deprecation, the above line should be changed to use the safer dictionary key retrieval method dict.get() so that a default value can be provided with dbt's default target path for backward compatability.

Filing this issue for visibility for now - I'm happy to work on this when I have some spare time
