feat: fully update http.py routes and related methods

[NeloBlivion]

• Removed create_guild, create_from_template and delete_guild - bots can no longer own guilds.
• Removed create_integration - bots cannot use this endpoint.
• Removed start_group - Bots cannot use this endpoint.
• Removed move_member and replace_roles - unused shortcuts for edit_member
• Removed bulk_edit_guild_application_command_permissions - disabled in Permissions V2
• Renamed change_my_nickname to edit_current_member
• Added icon to edit_channel for group DMs.

Considering Removal:

• set_voice_channel_status - functions, but not documented.

TODO:

• [ ] Add Modify Guild Incident Actions
• [ ] Update gateway methods to return full data
• [ ] Ensure all methods are available in http.py rather than scattered elsewhere
• [ ] Make method naming consistent
• More additions I haven't researched yet

If you have any additions/removals yourself or want to try renaming, feel free.

@Lulalaby do you have any info on set_voice_channel_status ? I remember you saying something at one point.

Look at the time lmao. Good night. Ping me in discord about it and I'll check when I wake up again 😂❤️

discord/discord-api-docs#6400 is still a draft. the endpoint is working since forever. dunno why it's still not merged. I'll ask
