release: v4.0.2 (#4801)

* Disable BROWSER env var

Right now the browser helper script does not actually work.  It seems
safer to skip this until we can fix it.

* Bump to 4.0.2

* Update changelog for 4.0.2

+### Fixed
+
+- Unset the `BROWSER` environment variable. This fixes applications that hard
+  exit when trying to spawn the helper script `BROWSER` points to because the
+  file is missing. While we do include the script now we are leaving the
+  variable omitted because the script does not work yet.
