refactor: Only look for metadata file in zip root (EME-606)

Changed extract_metadata_from_zip to only check for .sentry-cli-metadata.txt
in the root of the zip file, not in nested paths. This ensures we only find
one metadata file and makes the behavior more predictable.

Updated tests to verify that nested metadata files are ignored.
