feat(Interaction): add guild guard

[papsavas]

Please describe the changes this PR makes and why it should be merged:

closes #5809

This PR creates an inGuild() method both for Interaction and CommandInteraction checking if an interaction is used in a guild. Feel free to add suggestions, such as naming or implementation ,as i compeletely followed the ones from the issue

Status and versioning classification:

• Code changes have been tested against the Discord API, or there are no code changes
• I know how to update typings and have done so, or typings don't need updating
• This PR changes the library's interface (methods or parameters added)

I like the idea, but I'm not sure it should be relying on two other getters for the validation. guildID and member are the only ones you receive data for in the constructor.

channel and guild both assume this is a bot user with the GUILDS intent enabled, which means this could return false negatives if those caches aren't complete.

@monbrey in that case i suppose there is no need for an inherited method in CommandInteraction, just one <Interaction>#inGuild()
