feat(polls): implement Polls

[Snipy7374]

Summary

• Closes implement new Poll discord API feature #1175

Notes:

• Emojis in PollMedia doesn't work yet... idk if this is an issue on my code or on the API
• I still haven't tested sending Poll(s) on interaction responses and on Webhook(s) because that still returns 403 (Forbidden)
• I followed the discord api docs to name things, but if you have suggestions they are welcome, for example i feel like the new events names may be too long
• In the future the question field on Poll will be able to accept a PollMedia too, and PollMedia will likely supports new things
• Messages that contain a Poll can't be edited after sending (yet), tho in the future this shouldn't require much code changes
• Rn sending messages that contains Poll(s) can't have any other field set, this will not require any code change in the future since i'm not doing any check

Doubts:
I feel like i'm passing way too many arguments for the new events? What's your opinion? Solved

• Should we check for the number of answers the user is passing to construct the Poll? The maximum allowed is 10 answers per poll

I have a typing (skill) issue at poll.py/PollAnswer#245 what am i supposed to do there? Solved

Should we make answers and polls be EQ comparable in some way? (we could use the internal message object, if set, to check if two polls are equals) Doesn't make sense on second thought

Checklist

• If code changes were made, then they have been tested
  • I have updated the documentation to reflect the changes
  • I have formatted the code properly by running pdm lint
  • I have type-checked the code by running pdm pyright

• This PR is a breaking change (e.g. methods or parameters removed/renamed)
• This PR is not a code change (e.g. documentation, README, ...)

First off, thanks for implementing this, and sorry the review took so long! A bunch of other things unfortunately got in the way.

Many of these comments are simple documentation adjustments and can be committed as-is, some other parts are a bit more complex (as usual, coming up with a good developer interface is tricky).
There's still a bunch of bikeshedding to be done as you mentioned, so i've left out comments about a couple things that only make sense to talk about once everything else is taken care of, for now.

That said, a new permission and poll intents have been added to the api since, would be great to have them implemented here too.
