Originating from this issue: dbt-labs/dbt-core#2578

Key changes include the addition of a description attribute to generic tests, updates to the parser to handle this new attribute, and new functional and unit tests to verify the implementation.

Enhancements to Generic Data Tests:

• Added a description attribute to generic tests in core/dbt/parser/generic_test_builders.py to allow users to provide descriptions for tests, and ensured it is not passed into the test macro or name synthesis.
• Updated the create_test_node and parse_generic_test functions in core/dbt/parser/schema_generic_tests.py to include the description attribute in the test node metadata.
