• I added a very descriptive title to this issue.
• I included a link to the documentation page I am referring to (if applicable).

Issue with current documentation:

In the RunnableParallel usage example, the expected output is currently incorrect and does not reflect the behavior of the code.

Proposed fix:

Update the example in the code and documentation to reflect the correct, type-safe invocation (await) and the accurate output result.
