Missing/incorrect Rest endpoints

[Readeem]

Is your feature request related to a problem? Please describe.
I need access to many various Discord features for my project.
In this case, I need a possibility to fetch messages as described in Discord developer documentation,
but some of the endpoints from this library in rest/rest_enpoints.go are incorrect.

Describe the solution you'd like
Fix the GetFollowupMessage endpoint, which is currently defined as follows:

GetFollowupMessage    = NewNoBotAuthEndpoint(http.MethodGet, "/webhooks/{application.id}/{interaction.token}")

when it should be (according to Discord docs):

GetFollowupMessage    = NewNoBotAuthEndpoint(http.MethodGet, "/webhooks/{application.id}/{interaction.token}/messages/{message.id}")

Also, this library turns out to be missing endpoint GetWebhookMessage docs. I would like to see this endpoint implemented.

Since I'm making this feature request, I will also point at some of bugs that I've found in the codebase.
I don't know if they are still present in the main branch, but here they are:

1. gateway/gateway_events.go, line 587, EventMessageDeleteBulk struct, wrong json tag "id" instead of "ids". Docs
2. handlers/guild_scheduled_event_handlers.go, line 33, gatewayHandlerGuildScheduledEventDelete func, "event" parameter has "EventGuildScheduledEventCreate" type instead of "EventGuildScheduledEventDelete" type, which effectively prevents this event from firing.

Describe alternatives you've considered

Additional context
I wanna add some words of support for maintainers of this library, guys, you did a great job developing this library!
Modularity of disgo helps me a lot in my project. If only I had possibilities I would also consider supporting this library materially, but unfortunately I do not have ways to do so. Wish you the best.
