Blog example does not contain code

Bug description

In the blog example, posts/post-with-code says "This is a post with executable code.". However, that seems to be all the contents of the page. I was briefly confused, as I expected to find some executable code, and assumed at first something was wrong.

Could add some code to this page -- could either add code which isn't executed (which would always work), or add a jupyter example? Not sure what's prefered so not sure what suggested patch to make.

Steps to reproduce

Run quarto create project blog qqq, then look at posts/post-with-code/index.qmd

Expected behavior

Post contains some code after "This is a post with executable code"

Actual behavior

Open posts/post-with-code/index.qmd from a project created with quarto create project blog qqq and inspect the existing example content. Decide whether the example should contain non-executed code or a Jupyter example, then update the post so it includes code after the introductory sentence and verify the generated blog displays it.
