Font size of niche page titles is too big on small screen

[jimtyhurst]

Environment

• release candidate 2021-09-30.
• iPhone, Android

Expected Behavior

• The font should size proportional to the screen.

Actual Behavior

• The title wraps on niche pages:
  • https://marmaladeai.gatsbyjs.io/communities/digital-marketing
  • https://marmaladeai.gatsbyjs.io/communities/machine-learning

Possible Fix

• See how the text is sized according to screen size on the index.js page. For example, "Making freelancer networking easier" and "How freelancers connect with peers to share projects and stay up-to-date".
