Add remote helper text is mislieding

So, this is what the modal says:

That mades me thing that for adding a remote repository that uses ssh for auth I must use ssh: as prefix, but that is not true, I have to just add git@github.com:danielo515/project-name.git as usual. It does not throws any error, it just fails authenticating later, without any error message either. this can become very frustrating.

I don't know whether things have changed as I don't use projects, but I do remember at one point that it was necessary to use ssh://git@github.com/danielo515/project-name.git.
Note the subtle difference in the incantation, no colon.
