07-22-2024: Demote multiple h1s on homepage

[AnitaYCheng]

Expected Behavior

Each section heading on the TTS Handbook homepage should be h2 to be semantically correct and accessible to screen readers.

Current Behavior

Each section heading on the TTS Handbook homepage is actually an h1, resulting in 11 h1s on the homepage.

Possible Solution

The section headings look like they're automatically pulled in from a navigation file. There could be some kind of processing that "demotes" the headings before they're rendered on the homepage. (I have no idea how to do this in Eleventy, just wanted to put this out there!)
