class="note" inserts incorrect heading level

[mcking65]

In our css, we have a class note. This class adds a heading with content "Note".

The heading level of the Note heading is incorrect. It should be 1 level deeper than the level of the section that contains it. We are consistent with the use of sections.

For example, on the combobox pattern page, there are notes with heading level 5 that should have heading level 3 because the heading of the section that contains them is level 2.

Even though I have raised this in the site build repo, I am wondering if this shouldn't be addressed in the content repo. That is where we apply the CSS and so the it needs to be there too. It should probably work as desired even when viewing the raw content.

Fixed by changes made in w3c/aria-practices#2417.
The note class no longer triggers insert of a heading; the heading is provided by the content author.
