added wordle (use !wordle in a comment)

To play, enter "!wordle". Afterward, you will see a textbox and a funny little button with "GUESS" written on it.

You have 6 tries to guess the correct word.

After each guess, you get feedback for letters that are in the word and/or in the word and in the right space:

🟩 - correct letter and position

🟨 - correct letter, incorrect position

🟥 - incorrect letter

No reward so far. Have fun!
