#### Fix extra blank line between a list and an indented code block (#19154 by @YBJ0000)

Prettier forced two blank lines whenever an indented code block followed a list. The extra blank line is never semantically required and contradicts Prettier's usual behavior of collapsing consecutive blank lines into a single one.
