Discobot cannot distinguish between OneBox and linked text formatting

[Noble_Fish]

I think this step is intended to help users learn how to use OneBox, as it mentions

it’ll automatically expand to include a nifty summary.

However, users of the rich text editor often directly copy and paste text with links, which prevents the reply content from rendering as OneBox, yet discobot treats this situation as if there is no issue and proceeds to the next step.

I think this might be a result of the fix here: Discobot didn't recognize link in tutorial - #19 by martin

This commit fixes the issue by following a more simplified
approach, where we check for the existence of one of the
following links from the onebox instructions:

https://en.wikipedia.org/wiki/Inherently_funny_word
https://en.wikipedia.org/wiki/Death_by_coconut
https://en.wikipedia.org/wiki/Calculator_spelling

In your example, the link exists, but it’s not a onebox

It seems that a judgment for the ]( format is missing.

I went through the guidance process three times, and then decisively asked the user to complete the guidance using the Markdown editor in the very first message.
Although, even when using the Markdown editor, people need to use Ctrl+Shift+V when pasting text containing links to paste it as plain text rather than as link text with the page title as its content.
