[chore] update dependencies, bump to Go 1.19.1 (#826)

* update dependencies, bump Go version to 1.19

* bump test image Go version

* update golangci-lint

* update gotosocial-drone-build

* sign

* linting, go fmt

* update swagger docs

* update swagger docs

* whitespace

* update contributing.md

* fuckin whoopsie doopsie

* linterino, linteroni

* fix followrequest test not starting processor

* fix other api/client tests not starting processor

* fix remaining tests where processor not started

* bump go-runners version

* don't check last-webfingered-at, processor may have updated this

* update swagger command

* update bun to latest version

* fix embed to work the same as before with new bun
