Rename Halogen.VDom.Driver runUI #769

I find it pretty confusing that these two functions have the same name

• https://pursuit.purescript.org/packages/purescript-halogen/6.1.2/docs/Halogen.VDom.Driver#v:runUI
• https://pursuit.purescript.org/packages/purescript-halogen/6.1.2/docs/Halogen.Aff.Driver#v:runUI

Could for the next major release this be a breaking change to rename this function to something else? VDom has meaning in the context of UI but UI has no meaning in the context of VDom. Since the module name is already specified to VDom it is then logical that it doesn't contain something named with UI.
