`table-striped` is invisible in `darkly` HTML theme

[paddyroddy]

Bug description

Perhaps I was expecting too much, and have verified it works in the default theme. I am using darkly and the striped visually appears to have no effect.

Steps to reproduce

_quarto.yml

---
project:
  type: website

format:
  html:
    theme: darkly

index.qmd

---
format: html
listing:
  contents: .
  table-striped: true
  type: table
---

a.qmd

---
title: A
format: html
---

b.qmd

---
title: B
format: html
---

Expected behavior

I would expect alternating black and some shade of grey perhaps?

Actual behavior

All rows appear essentially the same - works in default theme

The class is still added to the listing (that part of the code is not aware of themes), so it must be the case that the .table-striped class isn't being handled correctly in dark themes. I haven't checked but I guess it adds a background color like rgba(0,0,0,0.1) to half the rows, and if the background is dark, this is either invisible or hard to see.

Yeah, I think it might be there. But so hard to tell.
