chore(scripts): allow --reset --up/--down to automatically run script (…

…#8826)

**[ISSUE]**
Honestly, kind of miss being able to use `lerna` for any kind of npm test through parameters with the old `builddown`. Wanted to be able to run something like `builddown build+test` or `builddown test`.

**[APPROACH]**
Added a `-r | --reset` flag to allow the `foreach.sh` script to reset and run in one line like `builddown`/`buildup`.

**[NOTE]**
Won't change anyone's current workflow because `--reset` is still in codebase.

Also arguments for the script aren't restricted by order (i.e. `foreach.sh --reset --up yarn build ` and `builddown yarn build --up --reset` will produce the same results)!
