Rename pinpoint pool

[sastels]

Summary | Résumé

We changed the language around pinpoint pools from "shortcode and longcode" to "shortcode and default" in this PR. Here we update the script that created these pools.

Note that I have manually changed the name of the pools in staging and production to default-pool, so this changed script should not change / create anything.
