crypto/tls: update ExampleDial with a valid root

When run as a separate program, the code in ExampleDial panicked due to
an expired certificate. Fixed this problem by replacing the expired
certificate with a valid one.

Also added a comment in the certificate to give a hint about why it
might fail in the future.

Fixes #35706
