SSL Error when trying to `.list_indexes()`

TL;DR

Fix: Community-verified causes for the SSL error, no single maintainer fix (closed with workaround). (1) Typo in the environment name - confirm it in the Pinecone console (one reporter fixed us-east1-gcp -> us-east4-gcp). (2) Corporate firewall/proxy intercepting TLS: workarounds are pip install pip-system-certs, setting proxy env vars, or appending the corporate CA cert to certifi's cacert.pem.
