Fix Astro SVG sprite sheet typo

 I usually run it out of band, immediately before actually building the website. My build command ends up looking something like `pnpm svg && pnpm build` (where those are both `package.json` scripts that build the sprite sheet and the rest of the site).

+No longer! At least for Astro sites. Arne Bahlo has a great tutorial on [statically generating open graph images using Astro API routes](https://arne.me/articles/static-og-images-in-astro), and I realized that the same technique will work to generate SVG sprite sheets.
 
 The key insight is that in static mode, [API routes](https://docs.astro.build/en/core-concepts/endpoints/#server-endpoints-api-routes) get rendered to static files. So this roughly the same workflow, except `svg-sprite` gets called programmatically instead of on the command line.
