[Bug]: Command with Option optional parameter won't register correctly

[Rutherther]

Description

I've noticed an issue when I wanted to create a command that has a required parameter as well as Option parameter that is optional. Remora will put the optional parameter as a first one (I suspect this is because Remora.Commands just puts Option parameters as first for easier handling) and that creates a problem when registering it as a slash command.

Steps to Reproduce

A command such as this will fail to register

[Command("echo")]
[Description("Send a message")]
public Task<Result> HandleEchoAsync
(
    string message,
    [Option('c', "channel")] Snowflake? channel = null
);

Expected Behavior

Registers the slash command correctly.

Current Behavior

Puts the Option as first parameter and results in APPLICATION_COMMAND_OPTIONS_REQUIRED_INVALID Required options must be placed before non-required options error.
