Use pnpm exec instead of pnpm dlx

[dtinth]

Whether to run pnpm dlx or pnpm exec should depend on whether to run the package from the registry or from local node_modules:

• pnpm dlx will always download from the npm registry
• pnpm exec will run the package from node_modules

(In contrary, npm’s npx will run the package from local node_modules if it exists, only install otherwise. This is not the behavior of pnpm dlx.)

So it should be something like this:

• Use pnpm dlx to run create-playwright
• Use pnpm exec to run playwright

nice! We should update tests/integration.spec.ts too I guess?
