Use tempdir for quarto preview instead of current workspace

[jooyoungseo]

From a screen-reader's viewpoint, html output that quarto preview produces is much more accessible when reviewing Jupyter Notebook (*.ipynb) files as opposed to conventional Jupyter Lab and VSCode interfaces. However, when I collaborate with other folks who do not use Quarto, I need to manually delete the preview html file and dependencies after each time I finish reviewing Notebook content.

Would there be any way to use temp directory to serve preview files instead of the current working directory?

We do have an output-dir option, but I believe it'll only work in website settings. Would it be possible to change where Jupyter lab or VS Code render instead?
