[td-tools] - 'webpack' is not recognized as an internal or external command

Recently I noticed the following issue when running
`npm run build` in the `/packages/td-tools/` folder

```
> tsc -b && webpack

'webpack' is not recognized as an internal or external command,
operable program or batch file.
```

Running `npm run build` in the root folder does not cause any issue. Is it a local issue on my machine (which I doubt) or is there anything that has been changed I am not aware of!?
