Minor syntax issue in asyncio howto guide example (strftime quote mismatch inside f-string)

Documentation

In the how to guide for asyncio titled A Conceptual Overview of asyncio, there’s a small syntax error in one of the code examples under the main() coroutine section.

    print(
        "Beginning asynchronous sleep at time: "
        f"{datetime.datetime.now().strftime("%H:%M:%S")}."
    )

Common mistake of nested double quotes inside strftime() within f-string. Could change it to single quotes.
Need to fix in L512 and L517.

This is valid since Python 3.12. See:
