[4.0.2] Fields don't save when editing them on the user profile

[vgmoose]

Thanks for your work on this plugin. I'm able to add my own fields in the Admin control panel, and get them to appear on the User's profile page. I can also see these fields in customFields in /api/config, which is good.

However, when entering or selecting any values on the user page, they don't appear to be saved anywhere. Maybe the save method is not being called? To be specific, I don't see where this method is supposed to be called: https://github.com/claude-wishnote/nodebb-plugin-custom-user-props/blob/main/library.js#L174
