Bug description

Hello. I'm getting the ERROR: API Error: 429 - Too Many Requests error when attempting to render a quarto document. My specific command is quarto publish Chapter_2.qmd. It looks like this is similar to Issue #6014.

Thank you!

Steps to reproduce

quarto publish Chapter_2.qmd

I've used multiple .qmd files and receive the same error.

Actual behavior

ERROR: API Error: 429 - Too Many Requests

Expected behavior

I expected it to publish to Quarto Pub. Also I am aware that Quarto Pub was down at some point today, so maybe that is related to the current issue.
