Add error message to output

[cagrimmett]

This is the output we see on the command line with an error:

❌ API error (500 https://opsoasis.wpspecialprojects.com/wp-json/wpcomsp/pressable/v1/sites): {"code":400,"message":"Bad Request","data":null}

This is what is available in the OpsOasis logs:

❌ API Client Error (Pressable): Bad Request - {"request":{"endpoint":"sites\/1258680\/clone","query_params":null,"method":"POST","body_params":"***","headers":null,"timeout":90},"response":{"status_code":400,"headers":{"server":"nginx","date":"Thu, 07 Nov 2024 14:48:59 GMT","content-type":"application\/json; charset=utf-8","content-length":"116","x-frame-options":"SAMEORIGIN","x-xss-protection":"0","x-content-type-options":"nosniff","x-permitted-cross-domain-policies":"none","referrer-policy":"strict-origin-when-cross-origin","access-control-allow-origin":"*","access-control-allow-methods":"GET, POST, PUT, PATCH, DELETE, OPTIONS, HEAD","access-control-request-method":"*","access-control-allow-headers":"Origin, X-Requested-With, Content-Type, Accept, Authorization","cache-control":"no-cache","strict-transport-security":"max-age=63072000; includeSubDomains","vary":"Origin","x-req":"iad1:3001:542f31a1-e125-4fe9-bee1-a6c661e5ce60"},"body":"{\"message\":\"There was a problem processing your request.\",\"data\":null,\"errors\":[\"Site name has already been taken\"]}"}}

This is the critical part that should also be added to CLI output to help us quickly debug:
errors\":[\"Site name has already been taken\"]}"}
