quarto project render empty if a parent dir is .hidden

Bug description

I was confused for a while why my project wasn't rendering anymore with no error without me making any changes to it. The reason turned out to be that I had moved the project to a path that had a directory that starts with a . (hidden).

I realize ignoring hidden directories in the project directory is intended per https://quarto.org/docs/projects/quarto-projects.html#render-targets, but perhaps it was not the intention to ignore everything if a parent directory is hidden? It might seem odd to work under a hidden dir, but in my case it was ~/.julia/dev/, where Julia package development typically takes place.

A simple way to reproduce (this is on Windows):

PS D:\temp\.hidden> quarto create-project myproject
Creating project at D:\temp\.hidden\myproject:
  - Created _quarto.yml
  - Created myproject.qmd
PS D:\temp\.hidden> quarto render myproject
PS D:\temp\.hidden> quarto -v
