Update townhall

Per discussions on the update museum icon ticket, I have updated the townhall, so that townhall is visually different compared to our museum icon.

I used the existing townhall icon as a guide for shape and pixel widths

I removed -11 when I just updated the other tickets, which I believe is causing this to fail at the moment (but will be fine once we update requirements). Let me know if I should add -11 back in.

I am actually going to close this PR and consolidate this update into the museum update PR
