Summary

#474

Doing this per module:

• nextcord
  • ext
    • commands
      • bot.py
      • cog.py (pass)
      • context.py (pass)
      • converter.py (pass)
      • cooldown.py (pass)
      • core.py (pass)
      • errors.py (pass)

  • audit_logs.py (pass)
  • auto_moderation.py
  • backoff.py (pass)
  • bans.py (pass)

(pass) means nothing in the module requires any changes.

Reviews and nitpicks are welcome.

This is a Code Change

• I have tested my changes.
• I have updated the documentation to reflect the changes.
• I have run task pyright and fixed the relevant issues.

Why is the TypeAlias called SnowflakeIntT, ending with T usually indicates a TypeVar. I'd prefer SnowflakeOrInt (might be better to use Snowflake | int in the future) or simply SnowflakeInt
