refactor: use @carbon/icons@10.8.0-rc.0

[metonym]

Closes #5

NOTE: Wait until @carbon/icons@10.8.0 is stable before merging. Release as 10.8.0-rc.0.

Changes

• Use build-info.json from @carbon/icons@10.8.0-rc.0 to generate icons
• Use moduleName from build-info.json (removes format.ts)
• Format template strings to avoid running prettier on written files
• Remove build:format-lib script
  • Cull devDependencies (npm-run-all, prettier-plugin-svelte, svelte)
