Fix release workflow false failure on successful dispatch

The line [ "\$HTTP_CODE" != "204" ] && cat ... returns exit code 1
when the condition is false (all dispatches succeeded). Since it
was the last command in the loop, the step reported failure.
Changed to if/then/fi which doesn't leak the test exit code.
