Add `page-navigation: true` with `sidebar: false`

Bug description

Currently it doesn't appear to be possible (afaict) to use page-navigation: true with sidebar: false.

I'm on MacOS

$ quarto --version
1.3.326

I've had to set sidebar: contents: auto with the styles for .sidebar-menu-container set to display: none with page-navigation: true to get a somewhat desirable behavior.

I'm also getting some inconsistent ordering for the page navigation. Sometimes it links to one page and other times it links to another.

I'm not sure if this should be a separate issue or not, but it would be nice if I could add contents to the sidebar from the YAML inside a single page.

• Please include a minimal, fully reproducible example in a single .qmd file? Please provide the whole file rather than the snippet you believe is causing the issue.
• Please format your issue so it is easier for us to read the bug report.
• Please document the RStudio IDE version you're running (if applicable), by providing the value displayed in the "About RStudio" main menu dialog?
• Please document the operating system you're running. If on Linux, please provide the specific distribution.
• Please provide the output of quarto check so we know which version of quarto and its dependencies you're running.

No source file, test, or minimal .qmd reproduction is provided. Start by reproducing the reported configuration with page-navigation: true and sidebar: false on Quarto 1.3.326, then trace the navigation and sidebar rendering paths. Done means page navigation works without a sidebar and its ordering is consistent.
