Handle more heading levels

colleenmcginnis commented 1 month ago

In support of https://github.com/elastic/observability-docs/pull/4230

In https://github.com/elastic/observability-docs/pull/4230 I noticed that page subheadings in deeply-nested pages weren't working as expected. The highest heading level I found was h10, but in this PR I added logic for up to h12. Here's an example of before/after this PR:

Before (`h10`, no formatting)	After (`h3`, with formatting)

Note: Headings beyond h6 are not technically valid HTML tags, but the build system will create them so we should handle them appropriately.
