Describe the style change

Presently black inserts a space between the "#" and "|" in Quarto metadata comments like #| label: cell1.

Examples in the current Black style

Space is inserted between the hash and the pipe:

# | label: cell-no1
# | echo: false

Desired style

No space between the hash and the pipe, which breaks document metadata parsing:

#| label: cell-no1
#| echo: false

Additional context

Quarto is the new(ish) replacement for RMarkdown and uses these kinds of comments for metadata in, e.g., Jupyter cells and so black breaks document rendering. It would be nice to keep #| together in the same way as a couple of other comment pairs are preserved.
