Fix script/zed-local on Windows (#38832)

Cole Miller created 

There's a mismatch between the URL used here and the one that's referred
to in `build_zed_cloud_url`, which prevents using the script on Windows.

A previous PR changed the script to use `127.0.0.1` instead of
`localhost` because of supposed URL parsing issues, but we were unable
to reproduce those.

Release Notes:

- N/A
