Silence failed auto update checks (#32696)

Don't immediately show "auto-update failed" errors in the status bar
when launching zed offline or when a periodic auto-update check is
triggered when you are offline. Manual checks (via menu or action) or
errors after the initial version check succeeds (download/extraction
failure) are unchanged.

Supersedes: https://github.com/zed-industries/zed/pull/32643

Release Notes:

- N/A
