chore: use npm 7 workspaces instead of lerna bootstrap

It's faster - running `time npm i` shows a nice speed up:

lerna

```
npm timing command:install Completed in 183859ms
npm timing npm Completed in 184077ms
npm info ok

real	3m4.246s
user	2m48.066s
sys	0m58.948s
```

npm7 + workspaces

```
npm timing command:install Completed in 101724ms
npm timing npm Completed in 101914ms
npm info ok

real	1m42.075s
user	1m52.422s
sys	0m46.022s
```

The downside is it requires npm7 - it's bundled with node 15 but will
require users up upgrade if they are using node 14 or below.
