fix(e2e): add tgz overrides to package.json pnpm.overrides post-migration

pnpm ignores pnpm-workspace.yaml overrides when pnpm.overrides exists
in package.json. vp migrate also overwrites overrides set before it
runs. Fix: add tgz overrides to pnpm.overrides AFTER migration so
@voidzero-dev/vite-plus-core@0.0.0 and @voidzero-dev/vite-plus-test@0.0.0
resolve to the locally built tgz files.
