`quarto.format.is_html_slide_output()` returns `true` for `format: html`

[cwickham]

isslides.lua:

Pandoc = function(content)
  quarto.log.output(quarto.format.is_html_slide_output())
end

notslides.qmd:

---
title: Untitled
format: html
filters:
  - isslides.lua
---

## Hello

On quarto render of notslides.qmd I get:

true
Output created: not-slides.html

Culprit might be:

quarto-cli/src/resources/pandoc/datadir/_format.lua

Lines 332 to 335 in 40b8b54

	isHtmlOutput = isHtmlOutput,
	is_html_output = isHtmlOutput,
	isHtmlSlideOutput = isHtmlSlideOutput,
	is_html_slide_output = isHtmlOutput,

That just looks like a bad copy-paste 🤦 . Thanks for the catch!!
