Loading saved workspace does not open sudo'd buffers

### I confirm that...

- [x] I have searched the [issue tracker](https://github.com/doomemacs/doomemacs/issues), [documentation](https://docs.doomemacs.org), [FAQ](https://docs.doomemacs.org/-/faq), [Discourse](https://discourse.doomemacs.org), and [Google](https://google.com), in case this issue has already been reported/resolved.

- [x] I have read "[How to Debug Issues](https://doomemacs.org/d/how2debug)", and will use it to provide as much information about this issue as possible.

- [x] The issue can be reproduced on the **latest** available commit of Doom.

- [x] The issue can be reproduced on a stable release of Emacs, such as 27, 28, or 29. *(Unstable versions end in .50, .60, or .9x)*

### Expected behavior

Loading a saved workspace should open or attempt to open tramp/sudo buffers.

### Current behavior

Currently, only buffers in the workspace which were not opened with sudo are restored, or sometimes none at all.

### Steps to reproduce

- create new named workspace
- create/open a file as normal user
- create/open another with sudo
- save workspace
- quit emacs then open emacs
- load the workspace you just saved
- notice that you are missing either the sudo buffer or both buffers
- weep gently

### System Information

https://gist.github.com/cccslater/e84753eea45ae84d303097a58f9221e0
I'm using emacs 30 day-to-day, this is the result of running 29 in a nix shell, hence there may be a slight config mismatch.

No source file, test, or entry point is identified. First reproduce the issue by saving and reloading a named workspace containing both a normal buffer and a TRAMP/sudo buffer, then trace the workspace restore path. Done means loading the workspace restores or attempts to restore the sudo buffer without regressing normal buffers.
