Fix release testing script (#43130)

Summary:

Various fixes/tweaks to the `test-e2e-local` script, impacted by recent changes, found during the release process:

- Fix typo in variable name for `circleciToken` arg.
- Relocate erroneously positioned `process.exit` call (a force exit around Verdaccio, which we will remove in future).
- Add notice on exit around Verdaccio server not being killed successfully (to do in T179377112).
- Switch from Yarn to npm for test project installation — Yarn 3 is not respecting `npmRegistryServer`, see yarnpkg/yarn#2508.
