Support aws-cli's AWS_CREDENTIAL_EXPIRATION envar

Feature Request

After merging and releasing aws/aws-cli#7398, the official envar supported by aws-cli is AWS_CREDENTIAL_EXPIRATION, so it should be supported as well (and replace other expiration envars when supported aws-related tools migrate to the new key):

❯ AWS_PROFILE=some-profile aws configure export-credentials --format env
export AWS_ACCESS_KEY_ID=[redacted]
export AWS_SECRET_ACCESS_KEY=[redacted]
export AWS_SESSION_TOKEN=[redacted]
export AWS_CREDENTIAL_EXPIRATION=2023-01-01T18:18:38+00:00

aws-vault also no longer uses AWS_SESSION_EXPIRATION so the duration is no longer displayed in starship prompt.

Quick temporary fix:

export AWS_SESSION_EXPIRATION="$AWS_CREDENTIAL_EXPIRATION"
