Add a blocking note for missing VignetteBuilder engine (#275)

# Pull Request

Following
insightsengineering/teal.reporter#288 this PR
add this note as a blocking note.

I added the note to several workflows (based on a [PR on other
repositories](insightsengineering/teal.reporter#291)),
let me know if this is a good approach.
