Fix:Broken External Footer Links due to relLangURL Filter

[aniket866]

Closes #554

Description

The footer layout filters external absolute menu links using the relLangURL filter.

• File Link: themes/microcks/layouts/partials/footer.html and (file:///c:/Users/Hp/microcks.io/themes/microcks/layouts/partials/footer.html#)
• Code Snippet:

  <a href="{{ .URL | relLangURL }}" title="{{ .Name }}">{{ .Name }}</a>

Why It Breaks

The footer contains absolute external links, such as the Linux Foundation privacy policy URL: https://www.linuxfoundation.org/legal/privacy-policy. Passing this absolute URL into the relLangURL filter corrupts the URL into a malformed relative path prefix (e.g. /https:/www.linuxfoundation.org/legal/privacy-policy). Clicking this link causes a 404 error on the local host instead of opening the external web page.

How to Reproduce

1. Build the website and scroll to the footer.
2. Click on the "Privacy Policy" or "Terms & Conditions" links.
3. Observe that the browser redirects to a broken 404 page on microcks.io rather than the external Linux Foundation website.
