Add connection popover issues and improvements
Testing Connections with the devel flatpak, there's a bunch of small UX issues with the add connection popover:
- The button says "connect", but when I press it, it adds the connection as opposed to actually connecting (I think that it should probably connect)
- The validation on the address is almost non-existent. Like, I can enter an address that is just "rdp://".
- When the popover opens, there's no visible label for the text field, owing to the fact that the hint isn't displayed while the field is focused.
- The learn more link looks and reads a bit oddly, and doesn't really do what it says it does (it takes you to a generic page of help about the app, as opposed to documentation specifically about the remote address).
I've updated the mockups to address some of these issues: https://gitlab.gnome.org/Teams/Design/app-mockups/-/blob/master/connections/connection-popover.png
