Currently when running tests with the --verbose flag, a nicely parsable json is immediately followed by the plain text summary, making the whole thing harder to parse.

Example:

$ fga model test --verbose --tests tests.fga.yaml | jq .
[ json blob ... ]
jq: parse error: Invalid numeric literal at line 2, column 2

Either one of the blobs should be send to stderr, the pretty print text should be suppressed, or at a minimum, a flag be added to optionally suppress the pretty print.
