✨ Add new tokenList command to list the token rules per guild

[sudovickili]

Fixes #12

Description:

Use /starry token-rule list 😄

Suggested QA:

• Use /starry farewell to remove bot, ensure that created roles have been removed
• Re-add the bot, expect a welcome message
• Use /starry token-rule add normally
  • Select "Choose a token" normally
  • Select "I need to make a token" normally
  • Select the DAODAO option normally
• Use /starry token-rule add incorrectly, expect helpful error
  • For the first two options, enter invalid cw20 address
  • For DAODAO option, type in an incorrect URL
• Use starry join flow from an account that doesn't have the added token, expect no roles when finished
• Use starry join flow from an account that does have the added token, expect all applicable roles to be added

Further QA:

• In the middle of a wizard, click on a button from another step, expect a helpful error or it to be ignored
• Reply to messages that are expecting emoji reaction inputs
• Kick starrybot (not farewell) and re-add, ensuring normal functioning
