Drop lerna in favour of wireit

[bennypowers]

Lerna's finally dead.

wireit is the new hotness from Google.

We should drop lerna (and npm-run-all) in favour of wireit

For context: the only thing we use Lerna for is parallel scripts, we don't use any of the monorepo management or publishing features.

Haha the link you posted now links off to a blog post saying basically "We're not dead yet!"

I've done some cursory explorations into wireit and it looks pretty great. I'm also a big fan of yarn 3 and their workspaces tooling.

Really interested to see which direction y'all decide to go in!

Will let you know here. I'm waiting on https://github.com/google/wireit/issues/33 before diving in
