Update the stale duration example.

The flag now defaults to 240*time.Second, but its help text still says e.g. 105s. Update the example to 240s or use a neutral example such as 4m.

In `@cmd/watch-termination/main.go` at line 37, Update the help text for the
graceful-termination-duration flag in gracefulTerminationPeriod so its example
matches the 240-second default, using 240s or a neutral equivalent such as 4m.
