Broken hyperlinks in home page

[claird]

Intra-page hyperlinks of the home page don't resolve, because target anchors are missing.

Example: https://pypi.org/project/black/#change-log does not display the Change Log section, because the Change Log heading lacks its intended anchor:

    ...
<p>More details can be found in <a href=CONTRIBUTING.md rel=nofollow>CONTRIBUTING</a>.</p>
<h2>Change Log</h2>
<h3>19.10b0</h3>
<ul>
    ...

They work at https://github.com/psf/black because of the way GitHub processes the Markdown.

Ha! I see. Thank you, Hugo.

No longer relevant as the TOC doesn't exist after my documentation reorganization effort: #2174.

Thanks for noticing though!

(p.s. I probably would've used <h1 id="change-log">Change Log</h1> to fix this)
(p.s.s I just noticed the changelog is referenced twice in the distribution's long description, we should probably fix that, that's a new issue tho)
