fix(simple-lock): mark @ckb-js-std/core as external to fix build error

[leothatguy]

Description

This PR resolves a build failure in the simple-lock dApp where esbuild was unable to resolve the @ckb-js-std/core dependency. By marking this dependency as external in the build script, we allow the bundling process to complete successfully, as this core library is expected to be provided by the runtime environment or handled separately.

Changes Made

What was the issue?

Fix the build error encountered when running pnpm build:
✘ [ERROR] Could not resolve "@ckb-js-std/core"
The Yarn Plug'n'Play manifest forbids importing "@ckb-js-std/core" here because it's not listed as a dependency of this package

What did you do?

Updated scripts/build-contract.js to include --external:@ckb-js-std/core in the esbuild arguments. This ensures that esbuild does not attempt to bundle this package, resolving the "Could not resolve" error.
