Unable to set permissions for slash commands

Description

Unable to set permissions for a slash command

Version

Cargo.toml is:

[dependencies.serenity]
default-features = false
features = [
    "client",
    "gateway",
    "rustls_backend",
    "model",
    "collector"
]
version = "0.11"

Example Output

Trying to set permissions for a slash command like so:

let permissions = GuildId::set_application_commands_permissions(&guild_id, &ctx, |commands| {
    commands
        .create_application_command(|permission| {
            permission
                .id(<my_command_id>)
                .create_permissions(|perm| {
                    perm
                        .kind(ApplicationCommandPermissionType::Role)
                        .id(<my_user_id>)
                        .permission(true)
                })
        })
})
.await.unwrap();

Generates a panic:

thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: Http(UnsuccessfulRequest(ErrorResponse { status_code: 405, url: Url { scheme: "https", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("discord.com")), port: None, path: "/api/v10/applications/<my_application_id>/guilds/<my_guild_id>/commands/permissions", query: None, fragment: None }, error: DiscordJsonError { code: 0, message: "405: Method Not Allowed", errors: [] } }))', src/main.rs:119:16

I validated which endpoint serenity is using to set permissions for slash commands, it is sending PUT https://discord.com/api/v10/applications/<my_application_id>/guilds/<my_gulid_id>/commands/permissions to update slash command permissions.

According to the discord docs this endpoint has been disabled with permissions v2 update to the api.

Serenity should be updated to edit each application command individually respecting rate limits.

I am happy to take this task on and generate a PR if no one else is looking at it currently.

This would also be helpful for me!
