build: update lerna to v7.4.2

Hopefully, this might solve our Node 20 errors...

Hmm looks like Nx uses JS syntax we can't handle 🤔

This sounds familiar, @mydea IIRC we encountered something like this before, right?

@Lms24 I didn't understand how this passes before Node 14, but not in Node 14.

I rebased this PR to check if things settled in the meantime. If not I'll close this in favour of looking into updating to lerna 8 in the future and as part of a general issue and PR cleanup initiative.

Ok, the Node 14 tests are still failing. Maybe we can revisit this after v9 where we drop Node 14 and 16 support. For now though I'll close this. Thanks for giving this a try, Yagiz!
