FEAT: Display total comments and number of replies for each comment

[muntaxir4]

Is your feature request related to a problem? Please describe.
Currently, the tutorial comments section does not display the actual total number of comments or the number of replies per comment. This makes it difficult for users to gauge engagement and discussions at a glance.

Describe the solution you'd like

1. Show total comments count at the top of the comment section.
2. Display the number of replies below each comment to indicate discussion activity.
3. Ensure this data updates dynamically when new comments or replies are added.

Additional context
This requires modifications in tutorialPageActions.js to fetch and store comment and reply counts in the state, as well as UI changes in Comment.jsx to display the numbers correctly.
