How to change point separator for the y-axis of a Plotly figure?

I've been working on a graph for days to summarize some results. However, I just got stuck trying to change the y-axis separator to "," instead of "."

I resorted to ChatGPT, as I don't have that much skill with the Plotly library, in Python, however, the solutions he presented still did not correct the problem.

In any case, here's the complete code for anyone who can help me. The graph is generated right after execution.

Greetings!
