v0.2.2

Release v0.2.2

Statically color the installed-plugin icon instead of following MOS's
theme "primary" color. manifest.json's icon field was the bare string
"mdi-robot-outline", which plugins.vue renders as a live-themed
<v-icon color="primary"> glyph - correct-looking on this instance only
because its theme primary happens to be the same orange (#E65100) the
plugin is meant to use, but not guaranteed for any other theme. Now
ships its own colored icon.svg (same asset/color as the Hub catalog
fix) at /plugins/ai-template-maker/icon.svg, served from staticfiles/
alongside the rest of the built frontend - so the icon renders the same
regardless of the viewer's theme.
