ts-node error on build attempt

[tomasmenezes]

I was trying to build the registry locally with the latest pnpm version but kept running into the 'Unknown file extension ".ts"' for "build-registry.ts" error (even with the passed esm flag). Also reproduced easily when creating a codespace on the main repo.

Full output for pnpm build:registry (or main build)

Hi,
This affected me as well. It seems to be an issue with ts-node and ESM, and fixing it may require removing "type": "module" from package.json. TypeStrong/ts-node#1062, TypeStrong/ts-node#2033, and TypeStrong/ts-node#1997 show a recurring pattern.

What I did to work around this was install tsx as a devDependency. tsx is an alternative typescript runtime for node, and it worked flawlessly for me.

pnpm add -Dw tsx
cd apps/www
pnpm tsx --tsconfig ./tsconfig.scripts.json ./scripts/build-registry.ts

Please let me know if this works for you. If it does, I will open a PR suggesting the switch.

@Gravy59 That seems to do the trick! Thank you
