Improve `strike` command response

[gabr1sr]

Description

The current strike command response doesn't cover all behaviors and need improvement.

Improvement

I suggest the following improvements:

• Warn when no users were provided
• Warn when caller isn't the one with the highest role compared to target users
• Don't show punished users response line when not needed
• Don't show not punished users response line when not needed
• Show strike reason
• Add emojis

Check-list

Users argument

• users must not be empty

Response

• Show warn message and return Ok(()) when user_ids is empty
• Show warn message and return Ok(()) when any target user's highest role is higher than yours
• Don't show punished users response line when punished_users is empty
• Don't show not punished users response line when not_punished_users is empty
• Don't show strike reason response line when reason is empty
