[Suggestion] Change textboxes for specifying paths to file explorer buttons

This would be in the settings for ComfyUI's location, and in the tab if ComfyUI is not found.

Not sure how practical this is for settings, but it makes sense for the install tab.

I have yet to come across an extension that bothers to add a button in the settings, people seem to be fine with how things are.
