Remove hamburger menu from tabs (#8067)

We added the menu button to both the tabs & where the subgraph menu
button was previously in order to get feedback on where this button
should be. We've received feedback that the one on the tabs is not a
common UX element, and that having both seems like a bug, and that the
one on the graph is prefered. Due to this, we're removing the one on the
tabs.
