Only override the first breadcumb link with 'Back to site' when it links to the homepage

Here is a patch to show the fix.

Created MR from the #2 patch. The patch is for Review.

Hi all! I've applied the provided MR as a patch and it applied cleanly with no errors. After applying the text Back to site has been replaced with the current active navigation text. However, I've noticed that the hyperlink for the Back to [active_navigation] always points to the last visited node as per the ginEscapeAdmin once in the gin/js/escape_admin.js file. I've attached screenshots for reference. So, I'm adding the needs maintainer review tag for the issue and moving to RTBC.

Thanks y'all 👏
