fix(ci): migrate build script approvals to allowBuilds for pnpm 11

pnpm 11 replaced onlyBuiltDependencies with the allowBuilds map. The
workspace still used the legacy key plus a broken allowBuilds section with
placeholder values, so every Deploy to GitHub Pages run failed at
pnpm install with ERR_PNPM_IGNORED_BUILDS (esbuild, lefthook) since the
pnpm v10 -> v11 bump (#433).

Replace the placeholder allowBuilds entries with real booleans for
esbuild, lefthook, and sharp, and drop the ignored legacy key.
