Fix functional tests error message

[nelsitoPuglisi]

Goal

Display the observed array when a functional test fails.

Previous message showing the expected array:

JSON validation failure reason: Array element not found in observed array: {"attributes":[{"key":"emb.session_id","value":"EMBRACE_TEST_IGNORE"},{"key":"emb.type","value":"ux.session"},{"key":"emb.private","value":"true"}],"events":"EMBRACE_TEST_IGNORE","name":"emb-session","span_id":"EMBRACE_TEST_IGNORE","start_time_unix_nano":"EMBRACE_TEST_IGNORE","status":"Unset","trace_id":"EMBRACE_TEST_IGNORE"}

New message showing the observed array:

Array element not found in observed array: {"trace_id":"2501394e59d5c219b11ef229e45260d6","span_id":"b6c8bf1e0c66ce41","name":"emb-session","start_time_unix_nano":1712840730495000000,"status":"Unset","events":[],"attributes":[{"key":"emb.session_id","value":"55D1F122D0E640CE866016F59F50A4A6"},{"key":"emb.type","value":"ux.session"}]}.Match failed for key: span_snapshots.
