The error message for code blocks should contain a snippet about editing your message

Am I understanding it right that the desired output would be something like:

Missing code block. Please use the following markdown:
'code here'
or
'''rust
code here
'''
(You can edit your original message and it will be reevaluated)

(I had to use single quotes instead of backticks due to formatting problems)
