build: use lerna 8 and still publish react wrappers

[Westbrook]

Description

• update to latest lerna
• rework the publish script to prevent the fact that /react is .gitignored by default from preventing lerna from publishing it

How has this been tested?

• [ ] Test case 1
  1. Do a publish
  2. Make sure it works
  3. Make sure that /react isn't actually added to the project
