Add the Friends (Social) tab back as a tab

Currently, the Social tab (formerly Friends) is tucked away at the corner of the play screen. This makes it harder to play with friends, and it is less accessible. Instead, the Social button should be added as a tab between the Worlds and the Realms tabs.

I think this is what the play screen should look like, with Social as a tab and not tucked away at the top, because who doesn't love easy access to friends? I made this post because the old UI used to have a Friends tab.
