Suggested Minor Correction for /2-Regression/4-Logistic/README.md

[misaraty]

Dear Developers,

I've been engaging with your ML-For-Beginners project on GitHub and found it immensely helpful. Thank you for creating such valuable resources for beginners.

I would like to suggest a minor correction in the code found in this section. The existing code snippet:

palette = {
    0: 'orange',
    1: 'wheat'
}
sns.swarmplot(x="Color", y="ord__Item Size", data=encoded_pumpkins, palette=palette)

produces a ValueError due to mismatched dictionary keys. The keys should be strings to match the data types in the 'Color' column. Here is the corrected code:

palette = {
    '0': 'orange',
    '1': 'wheat'
}
sns.swarmplot(x="Color", y="ord__Item Size", data=encoded_pumpkins, palette=palette)

Thank you for considering this correction.

Best regards,

Misaraty
