fix(ci): point Cloudflare deploy at adapter-cloudflare output dir

The docs adapter switched from adapter-static to adapter-cloudflare in
1a25f6c, but the release workflow still ran `pages deploy build`.
adapter-cloudflare writes to `.svelte-kit/cloudflare/` (matching the
`pages_build_output_dir` declared in apps/docs/wrangler.toml), so the
deploy step ENOENT'd on the missing build/.
