Attempting to `.get_partial_message()` from a `PartialMessageable` results in an Exception

Summary

Exception thrown when trying to construct a PartialMessage from a PartialMessageable

Reproduction Steps

A help file for .partial-objects in the Pycord Discord states the following:

Partial Objects

These can be used to make API calls when you have channel id and/or message id, and you don't want to rely on the cache to have their objects.

Methods which can be used on them are
Partial Messageable (analogous to a Channel) - Docs
Partial Message (analogous to a Message) - Docs

Example Usage:
async def star_message(channel_id: int, message_id: int):
# Get Partial Messageable object
partial_channel = bot.get_partial_messageable(channel_id)

# Get Partial Message
partial_message = partial_channel.get_partial_message(message_id)

# Add a reaction
await partial_message.add_reaction(":star:")

The issue is that PartialMessage checks the incoming type, and PartialMessageable, as constructed and returned by .get_partial_messageable(), is not on that list.

Minimal Reproducible Code

async def star_message(channel_id: int, message_id: int):
    # Get Partial Messageable object
    partial_channel = bot.get_partial_messageable(channel_id)

    # Get Partial Message
    partial_message = partial_channel.get_partial_message(message_id)

    # Add a reaction
    await partial_message.add_reaction(":star:")

await star_message(881224361015672863, 1273298167768682611)

Expected Results

A PartialMessage object is provided for further interaction

Actual Results

An exception is thrown due to PartialMessageable not in the list of valid channel types for PartialMessage

Intents

any
