In quarto render, "--output -" is incompatible with "--embed-resources"

Bug description

In quarto render, simultaneous use of the options --output - and --embed-resources fails with an error (file not found). This error occurs after the HTML file is generated and printed to stdout.

Steps to reproduce

$ touch example.qmd

$ quarto render example.qmd --output -
# ... runs without errors, printing HTML to stdout

$ quarto render example.qmd --output - --embed-resources
# ... the HTML is printed to stdout without issue, but then an error appears:
ERROR: NotFound: No such file or directory (os error 2)

Reproduce the failure with quarto render example.qmd --output - --embed-resources, then inspect the post-processing path named in the trace, especially pandocIngestSelfContainedContent and onPostProcess. Trace how the output path is handled after HTML is written to stdout. Done means the command exits without the file-not-found error while still printing the HTML.
