[Bug]: og:image meta tag points to homepage URL instead of an actual image

[Sakshi-Sharma08]

Bug Summary

og:image meta tag contains the homepage URL instead of a real image, causing no preview image when the site is shared on social media.

Bug Description

The og:image meta tag on the homepage is set to the
homepage URL instead of an actual image file.

Current (wrong):
og:image = "https://ajay-dhangar.github.io/algo/"

Expected (correct):
og:image = "https://ajay-dhangar.github.io/algo/img/logo.png"

Steps to Reproduce

1. Go to https://ajay-dhangar.github.io/algo/
2. Right-click anywhere → View Page Source
3. Press Ctrl+F and search for "og:image"
4. See that the content value is the homepage URL, not an image

Expected Behavior

The og:image should point to a real image file so that
a proper preview thumbnail appears when the site is
shared on WhatsApp, Twitter, LinkedIn, or Discord.

Actual Behavior

No preview image appears when the site link is shared
on social media because og:image points to the
homepage URL instead of an image file.

Hi @ajay-dhangar! 👋

I found this bug while exploring the Algo platform.
The og:image meta tag on the homepage is currently
pointing to the homepage URL instead of an actual image,
which causes no preview thumbnail to appear when the
site is shared on social media platforms like WhatsApp,
Twitter, LinkedIn, or Discord.

I would love to work on this issue and submit a fix as a PR.

The fix involves updating the docusaurus.config.js file
to point og:image to a real image file.

Could you please assign this issue to me?

Thank you!
