fix(0.81): fix yarn constraints failures after release bumps

Mark root monorepo and nx-release-version packages as private with a
fixed version of 1000.0.0, decoupling them from the release versioning.
Add a yarn constraint to enforce this.

Previously, nx release only bumped packages/react-native and
packages/virtualized-lists, leaving these internal packages behind and
causing yarn constraints to fail.
