Replace rustls-native-certs with rustls-platform-verifier (#24656)

closes https://github.com/zed-industries/zed/issues/19620.

I am not 100% sure on how to test this though. @elithrar: would you mind
giving this branch a shot and seeing if it works for you? I kicked off
bundling for this pull request and you should be able to download a DMG
from the CI artifacts as soon as it's done building.

Release Notes:

- Fixed a bug that caused OS-level CA certificate bundles to not be
respected.
