fix(doctor): point repository metadata at the monorepo

The package moved into packages/doctor but its manifest still named the
archived nativescript-doctor repo. npm rejects a --provenance publish when
repository.url does not resolve to the repo the workflow ran in:

  422 Unprocessable Entity - Error verifying sigstore provenance bundle:
  package.json: "repository.url" is
  "git+https://github.com/NativeScript/nativescript-doctor.git", expected to
  match "https://github.com/NativeScript/nativescript-cli"

repository.directory tells the registry which subtree the package is built
from. bugs and homepage followed the same move.

CHANGELOG.md keeps its nativescript-doctor links - those commits and issues
only exist there.
