separate spicetify menu items from spotify ones

[ohitstom]

📝 Provide a description of the new feature

for example:

• check through list of all li items
• pick out the one containing an svg with aria-label External link
• append vvMORUKtQKpQcpQ992bR classname to its button

alternatively:
or via some other method idk how menu items and context menus now work, potentially create a store of all menu items registered like we do with topbar buttons and if its the first one to be registered add a border to the bottom of it instead? that approach could also work for normal context menus that way!
