Stop hiding Activity Bar in ISE Mode

The user can, if they really wish, do this with
`workbench.action.toggleActivityBarVisibility`, but at least in the
latest Insiders it does not appear we can set this to `false` any more.
Moreover, it's a confusing UI change to make even for the sake of an
"ISE-like" experience. Simplest answer seems to be to stop trying to
hide it so as to unblock our CI.
