Update example.com zone SOA expire value

The example.com zone file given in the "Configurations and Zone Files"
chapter has an SOA expire of 3 weeks, which is not a multiple of
the default signatures-validity value. Adjust the SOA expire so that
it is much lower than the signatures-validity default.
