fix(lambda-nodejs): pnpm exec command (#14954)

Fix #14757

Expands on #14772

Currently get the following error when bundling with `pnpm-lock.yaml`
```
ERROR   ERROR  Unknown options: 'bundle', 'target', 'platform', 'outfile', 'external:aws-sdk'
```

----


Switch from `pnpm run esbuild` to `pnpm exec esbuild --` to properly enable esbuild with `pnpm`

`pnpm run` only supports running commands defined in the package's manifest file - [docs](https://pnpm.io/cli/run)

`pnpm exec` supports executing a shell command in scope of a project - [docs](https://pnpm.io/cli/exec)
