gui: Fix connection type icon width (fixes #8592) (#8644)

The connection type icon comes from Bootstrap. As such, it does not
follow the same dimensions as the other GUI icons, which come from Fork
Awesome. Thus, add left and right margin to make its width roughly the
same as the other GUI icons, which fixes its alignment in relation to
text.
