Auto install front end updates.

### Feature Idea

Can you add an if/then statement to ComfyUIs boot(or when 'Update All' is run) to automatically run the pip command to install the new front end if needed?

if installed version < current version then python.exe -m pip install -r requirements.txt
... the rest of the boot process...

You already have a check in place to let people know when an update is needed, this could automatically run if an update is needed.
