Description

Explains the theme_icons property of the action manifest key in "Your second extension," and links the beasts-32-light.png icon used in the manifest.json example so readers can download it.

Motivation

The manifest.json sample references theme_icons with a beasts-32-light.png icon, but the article's explanation of the action key never mentions theme_icons, and no download link for beasts-32-light.png is provided anywhere in the article. Readers following the tutorial hit a missing icon with no explanation of why it's missing or where to get it (it's optional and falls back to beasts-32.png, but that isn't stated).
