Describe the problem

Scores that contain . are not accessible when I download traces from the traces table.

Reproduction steps and code snippets

No response

Error logs or stack trace

Step 1: Log data using:

client = opik.Opik()
client.trace(
    name="test",
    input="testing",
    feedback_scores=[
        {"name": "some_score", "value": 0.1},
        {"name": "some_score.with_dot", "value": 0.2},
        {"name": "some_score-with_dash", "value": 0.4}
    ]
)

Step 2: Navigate to the Opik UI, select the trace and download it as a json
Step 3: View the trace data and notice the missing scores. This is what I get when I download the trace specified above as a JSON:

[
  {
    "id": "0195f649-3cb0-7c6b-bc04-b5bbc30b379b",
    "name": "test",
    "input": "testing",
    "output": "",
    "duration": "",
    "comments": "",
    "some_score": 0.1,
    "some_score-with_dash": 0.4,
    "with_dot": "-",
    "User feedback": "-"
  }
]

-> Bug: some_score.with_dot is not present in the exported file
