sidebarDepth: 0 not working in YAML

• I confirm that this is an issue rather than a question.

Bug report

When using sidebarDepth: 0 in a page YAML the header links keep being displayed.

This is caused by the coalesce assignment in SidebarLink. Concretelly this piece of code:

    const configDepth = $page.frontmatter.sidebarDepth
      || sidebarDepth
      || $themeLocaleConfig.sidebarDepth
      || $themeConfig.sidebarDepth

Steps to reproduce

Just place the value in the top of the page:

---
sidebarDepth: 0
---

I have a repo with the current issue in my repo but I will try to find a workaround so can be fixed when you tested.

What is expected?

To do not show header links

What is actually happening?

It is showing h2 headers

If you want to hide the sidebar, just set sidebar to false via frontmatter:

---
sidebar: false
---

You didnt even bother to read the issue, ut is good to know because next time I will not bother to open it.

I do not want to hide the side bar, what i dont want is to show page header links beyond level 0

It looks like this was tagged for 1.0.3 but I don't see it in that release. Am I missing something?
