Add a Copy as Markdown button on error pages

[michaelnjuguna]

It would be useful if the default AdonisJS error pages included a Copy as Markdown button. This would allow developers to quickly copy errors in a clean markdown format for debugging, sharing, and especially for providing context to LLMs.

Hello 👋

Can you please share what the markdown output should look like and what information should it contain? Is there any standard that we could follow?
