Issue:
`markdown.marp.pdf.outlines` option to generate outlines in PDF
[Marp CLI v2.2.0](https://github.com/marp-team/marp-cli/releases/tag/v2.2.0) has new `--pdf-outlines` option to generate outlines in output PDF from slide pages and Markdown headings. When bumping dependency of Marp CLI, it is better to add corresponding configuration `markdown.marp.pdf.outlines`.

- **`markdown.marp.pdf.outlines`**
  - `off`: No outlines added to PDF. (default)
  - `pages`: Outlines based on slide pages will add to PDF. (`--pdf-outlines --pdf-outlines.pages --pdf-outlines.headings=false`)
  - `headings`: Outlines based on Markdown headings will add to PDF. (`--pdf-outlines --pdf-outlines.pages=false --pdf-outlines.headings`)
  - `both`: Outlines based on both of slide pages and Markdown headings will add to PDF. (`--pdf-outlines`)

Pull request:
Add `markdown.marp.pdf.outlines` option
Resolves #381.
