Publish action: ERROR: The specified path (.) is not a website, manuscript or book project so cannot be published.

I have a pretty simple quarto->revealjs repo:
https://github.com/TheJacksonLaboratory/intro_qupath_workshop
I'm using a vanilla GitHub action (checkout, quarto/setup, quarto/publish):
https://github.com/TheJacksonLaboratory/intro_qupath_workshop/blob/main/.github/workflows/quarto_publish.yml

A change in the past few months has resulted in the Publish action failing:
https://github.com/TheJacksonLaboratory/intro_qupath_workshop/actions/runs/10581001442/job/29317260553

It appears that the default path used by the publish action is no longer OK for quarto? I assume due to a quarto version update?

quarto-actions/publish/action.yml

Lines 31 to 34 in 6cb292a

	path:
	description: 'Subdirectory containing the quarto project to be published'
	required: false
	default: "."

As a workaround, I can specify index.qmd as per:

Could it be related to not having a _quarto.yml and instead everything in the single index.qmd header:
https://github.com/TheJacksonLaboratory/intro_qupath_workshop/blob/15bf643c4efc9927151df4b934ad66f9bdd7bd03/index.qmd#L1C1-L15C4
It used to work with quarto <1.5
