Update set-version script to version private packages and workspace deps

Summary:
Addresses a gap when using the `set-version` script to update all packages on `main` (i.e. post branch cut):
- Package versions were not being set consistently. It is safe to version all workspace packages, including `"private"`.
    - Our publishing workflow is independent from this, and only considers public packages for submission to npm.
- We also need to update the root `package.json`, which includes `devDependencies` referencing workspace dependencies.

Unblocks facebook#43132.
