refactor: request all webhooks at once, match by name

* request all webhooks in a single call rather than per configured webhook

* Enable support for multiple identical test bots
sharing the same webhook

This should prevent the limit of 10 webhooks per channel from being reached
without needing to share a specific guild configuration for the PyDis
staff test guild
