This fixes #13360 by adding fallback directories that are searched by the CLI if the main executable cannot be found in the `libexec` directory. Release Notes: - Added the fallback directories `lib/zed` and `lib/zed-editor` for the main executable search in the CLI ([#13360](https://github.com/zed-industries/zed/issues/13360)). --------- Co-authored-by: Conrad Irwin <conrad.irwin@gmail.com>
