Closes https://github.com/zed-industries/zed/issues/42360 If updating a language server takes longer than 10 seconds, we now fall back to launching the currently installed version (if exists) and continue downloading the update in the background. Release Notes: - Improved language server updates for slow connection, now Zed launches existing server if the update is taking too long. --------- Co-authored-by: Piotr Osiewicz <24362066+osiewicz@users.noreply.github.com>
