Improvements to Bengali Streamlit translation

[jojo96]

Hello

Thank you very much for accepting my contributions. Could you address the following minor issues:

Day2.md is not yet translated, could you help to translate this? In Day27.md, the bottom link has an extra space in the middle of the link (Line 269). Thus, please delete the extra space

I addressed both of these issues.

Hi again Ujjayanta, Could you re-deploy the app and make sure that it is set to Public, it is currently not public. Thanks!

I am not sure about this. I just deployed the app from share.streamlit.io and the link is https://jojo96-30days-bengali-streamlit-app-cy9uyl.streamlit.app/

Should it do the trick?
