[A11Y] Add `aria-label` attributes to all social media links in the Footer

[Aditya948351]

Screen readers currently announce social media icon links as empty links because they only contain SVGs. Navigate to src/components/layout/Footer.tsx and ensure every <a> tag wrapping an icon has a descriptive aria-label (e.g., aria-label="Visit our GitHub").

Hi @Aditya948351, I'd like to work on this issue. I'll add descriptive aria-label attributes to all the social media <a> tags in src/components/layout/Footer.tsx so screen readers announce them properly instead of as empty links. Please assign this to me.
