Fix apiview reqs install on Python 3.13 and update version calculation logic (#47608)

* Fix apiview reqs install on Python 3.13

lazy-object-proxy==1.10.0 has no cp313 wheel, so pip builds it from source. The isolated build env fails to fetch setuptools_scm from the private feed (401 -> interactive prompt -> EOFError). Pre-install build deps from PyPI and use --no-build-isolation as a workaround until lazy-object-proxy works on Python 3.13.
