fix(pkg): fix esm export

[baumstern]

This PR ensures ESM modules are exported correctly, fixing the issue where using Remix with Vite leads to failed attempts to load CJS modules, as demonstrated in the case below:

(node:56711) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
2:26:48 AM [vite] Error when evaluating SSR module /app/routes/_index.tsx: failed to import "@hypercerts-org/sdk"
