clip error

Sadly my SSD died and I had to reinstall forge. Now when I start the tool, it states that it can not install clip.

I downloaded this file: [Forge with CUDA 12.1 + Pytorch 2.3.1](https://github.com/lllyasviel/stable-diffusion-webui-forge/releases/download/latest/webui_forge_cu121_torch231.7z)
and unpacked it into a folder "forge" (like I did in the past) and ran update.bat then run.bat.

```cmd
Installing clip
Traceback (most recent call last):

My workaround is to uncomment the clip check in launch_utils.py

```python
# if not is_installed("clip"):
# run_pip(f"install {clip_package}", "clip")
# startup_timer.record("install clip")

# if not is_installed("open_clip"):
# run_pip(f"install {openclip_package}", "open_clip")
# startup_timer.record("install open_clip")
```

But this does not look right for me..

**System:**
intel 12900k cpu
nvidia 3080ti
Windows11
_dunno if this is even important :D_

Start in modules/launch_utils.py at prepare_environment() and the run_pip() call that installs clip, then compare the reported command with the bundled Python environment launched by launch.py and run.bat. Reproduce the failure on the listed Windows setup if possible; done means a fresh installation handles the clip dependency without manually commenting out the checks.
