Headings inside components are not in the table of contents

### What You Are Seeing?

If a heading is inside of a component and imported into an .mdx file, that heading does not appear in the table of contents for the page.

### What is Expected?

Unfortunately, this is working as designed. Astro does not natively support this. Thinking about this issue more, headings should _not_ be inside of components at all. A big reason for this is that the heading level may be different based on the content of the page. Using the wrong heading level will hurt accessibility.

It has been decided that instead of placing headings inside of components, all heading should be in the original .mdx file, and only the content be pulled into a component. This will give us:

1. Control over the heading levels.
2. It will automatically be added to the TOC like other headings.

2. Notice the heading "Chocolatey Component Package Dependencies" is not in the right side TOC.
