swapping Usage content to not be header links

[rouzbeh84]

this is for #1306

Unless I'm missing something Usage links but the Examples subheaders are being pulled into sidebar when they shouldn't be?

screen recording of Usage working as expected

So I think this will fix this instance but I think maybe the title I used for that issue caused some confusion. By "Link Usage" I meant using links in headers shouldn't display the actual markdown in the sidebar:

We may have to hack our markdown utility again (ugh) to fix this globally. However, I may merge this fix for now and come back to it down the road as I think we'll be updating our whole markdown parsing process soon anyway (see webpack-contrib/webpack-defaults#73).

@skipjack totally agree on the header links thing. we'll see how it shakes out re:

But doc linking to a linked header could be as simple as adding the link title twice, once as an id as well as href when processed? Just a suggestion as I'm sure that'd probably have unintended implications in other parts of the documentation.
