prql: mdbook-admonish not found in Dev Container

What happened?

Solution: Install mdbook-admonish (see steps below.)

Since around the 0.9.0 timeframe, I have noticed that the md-admonish notes are not being displayed properly in the documentation under development.

Things look OK in the production documentation: for example, the Literals page (https://prql-lang.org/book/reference/syntax/literals.html) shows the blue heading for an adminish note as expected.

But the same page rendered by task run-book in the Dev Container shows the same text rendered in monospace font, with no special header.

What other information can I provide to troubleshoot this? Thanks.
