[core-workflow] Use something other than an In-joke for Trigger Phrases

[Donald Stufft]

Currently the workflow for CPython development requires people to say 'I didn't expect the Spanish Inquisition’ in order to request a re-review of their work. Can we please use a phrase for this that makes more sense rather than, as Alex put it, “magic inside baseball language”.

In jokes can be fun when they’re able to essentially be just noise to people who aren’t part of the in crowd (e.g. the bot name being one is fine) but they’re kind of crummy when a core part of the developer experience or API. Leave it in as an Easter egg if you like (and probably should for backwards compatibility anyways), but please make something else be the primary phrase.
