AoC: Convert commands to hybrid slash commands (ephemeral where reasonable)

[janine9vn]

The following commands should be converting to hybrid slash commands:

• daystar
• leaderboard
• global leaderboard
• stats
• countdown (Turn AoC commands into hybrid commands #101)

The following commands should be converted to slash-only and be ephemeral:

• connect/link
• disconnect/unlink

The following commands should only be able to be run in advent-of-code-bot-commands, sir-lancebot-playground, or bot-commands. If they are tried to run elsewhere, they should redirect to advent-of-code-bot-commands and let the user know.

• daystar
• leaderboard
• global leaderboard
• stats

@n0Oo0Oo0b would you like to split this issue up into tasks? There seems to be a lot of commands / tasks involved and I'd be willing to take up some of that work if you don't mind.

Sure, how should I split the tasks?

@n0Oo0Oo0b I think splitting it up the same way Kat's done it should work. We could make PRs for each of them, so they can be reviewed more effectively. For instance, a PR titled Convert &daystar command into a hybrid command. This way we can get multiple people working on this issue at once as well

[n0Oo0Oo0b]

Seems like converting all of them in one go would be pretty straightforward (see #101 (comment)), so I don't think it's necessary to split this issue up anymore.

@janine9vn just wanted to ask, what's the reasoning behind making only the link/unlink commands fully slash commands, and making the other hybrids?
