Quando tento o comando git push -u origin main recebo esta mensagem he authenticity of host 'github.com (20.201.28.151)' can't be established. ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU. This key is not known by any other names. Are you sure you want to continue connecting (yes/no/[fingerprint])? Porém eu já fiz o procedimento para criar a chave SSH, então, o que pode ser e como resolver?
