Note: I've asked @oanaianc to test whether the webhooks still work after this change - I'm concerned they won't, because the ktor-server-jetty package references jetty 9.x. Please don't merge this until that test is complete.

Note: this now needs the ktor from my PR at https://github.com/ktorio/ktor/pull/3015.

lgtm. wish i remembered what jersey was used for...part of me wonders if that dep might be obsolete.

Actually it looks like the jersey.version variable isn't referenced anywhere, so I can remove it.
