Provide full channel object in INTERACTION_CREATE instead of only an inconsistent partial one

[mccoderpy]

As the interactions model is meant to be used in both ways, with and without gateway, it is very uncomfortable that we only get a partial channel object in the interaction object.

Especially for pure HTTP interactions it would be useful to get this full object instead of only a partial one where you don't even know
what fields you can get from it except the "guarantied" ones: type and id

For example, a user of my Lib got an exception because the parent_id in a thread was missing, but when I tested it, it was present:

{
    "type": 11,
    "total_message_sent": 3,
    "thread_metadata": {
        "locked": false,
        "create_timestamp": "2023-06-29T05:40:12.644000+00:00",
        "auto_archive_duration": 10080,
        "archived": false,
        "archive_timestamp": "2023-06-29T05:40:12.644000+00:00"
    },
    "rate_limit_per_user": 0,
    "permissions": "140737488355327",
    "parent_id": "1116383616616906892",
    "owner_id": "693088765333471284",
    "name": "[Bug]: Fix utils._unique to always return a list when the input is not list set or tuple",
    "message_count": 0,
    "member_ids_preview": [
        "693088765333471284"
    ],
    "member_count": 1,
    "last_message_id": "1126053501705932840",
    "id": "1123850388060254268",
    "guild_id": "852871920411475968",
    "flags": 0,
    "applied_tags": [
        "1116384856633507912",
        "1116387930857029733",
        "1116384337538076856"
    ]
}

So I think it would be the best to give a full channel object or at least do not (sometime) skip fields that are not optional for a channel type.

I think you would be more likely to get what you need if you request the specific fields you need, with use cases, instead of the whole object

[mccoderpy]

Well that would take a bit to collect all the fields with their use case... That's why I wrote that (also, because it would be the only solution that would not require additional models in most libs):
