Display @code_warntype output in docs

[gdalle]

Hi!
How would one go about displaying the output of @code_warntype in a Documenter-generated webpage?
From what I can tell, there are two obstacles:

• @code_warntype prints its output in the REPL instead of returning it (probably easy to overcome)
• I sometimes encountered a weird error to the tune of “code_warntype not defined” when trying to expand Markdown files. I generate these Markdown files from Literate.jl, so the MWE is a bit tedious but if no one has encountered this error I can try to come up with one

I think this is because @code_warntype is exported by InteractiveUtils, which is loaded by default only in interactive sessions. An explicit using InteractiveUtils somewhere in your code should solve the issue.

Sounds like the solution, thanks!
