Made links clickable in post content

[Kalyan-velu]

Closes #472

Implementation:

• Created a function or utility that scans the caption and posts content for any URLs.
• Identified and extracted the URLs using regular expressions.
• Generated clickable HTML hyperlinks for each identified URL.
• Replaced the plain text URLs with the corresponding clickable links in the rendered caption or post.
• Ensured that the links open in a new tab or window to avoid disrupting the user's browsing experience.
