Update docs about how to get temp credentials when authed as SSO

[revmischa]

I did not find this info when looking at these docs and it would have been really help to have some note about aws configure export-credentials

Maybe it could be added to the docs?

• https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_use-resources.html
• https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-sso.html#cli-configure-sso-login
  • "The authentication token is cached to disk under the ~/.aws/sso/cache directory with a filename based on the sso_start_url."

Hi @revmischa, thanks for reaching out. I definitely agree it'd be helpful to have export-credentials mentioned somewhere in the CLI user guide. I've forwarded this feedback to the CLI documentation writer, and will leave this issue open for tracking until it's done. Thanks!
