Update pytest examples for contributors

[dbeatty10]

resolves #9788 (again)

Problem

These pytest example commands don't work for me when following the contributing instructions, presumably because these tests moved to the dbt-adapters repo:

# run all unit tests in a file
python3 -m pytest tests/unit/test_base_column.py
# run a specific unit test
python3 -m pytest tests/unit/test_base_column.py::TestNumericType::test__numeric_type
# run specific Postgres functional tests
python3 -m pytest tests/functional/sources

Instead, I get errors.

Solution

These would probably be better examples to use (and they worked for me):

# run all unit tests in a file
python3 -m pytest tests/unit/test_invocation_id.py
# run a specific unit test
python3 -m pytest tests/unit/test_invocation_id.py::TestInvocationId::test_invocation_id
# run specific Postgres functional tests
python3 -m pytest tests/functional/sources

Testing

Manual testing of the code examples within CONTRIBUTING.md is sufficient to complete this issue since it doesn't affect the delivered code.

I tested that the updated example commands run without any errors.
