Fix bing Temporary Patch (gh-pages)

[henilp105]

This PR is to resolve #222 , Please refer : https://fortran-lang.discourse.group/t/4942

This is a temporary patch to fix the bing directly via gh-pages as it seems the most likely cause could be HTML redirection , as we don't have the functionality to add 301 Redirect in gh-pages, thus this PR is a temporary fix to this redirection bug , and this same method of redirection is also used in the fpm-docs repository and we seem to reproduce the same problem for the fpm-docs repository as well.

Thanks and Regards,

Henil @henilp105, would it be possible to move the English language tree to fortran-lang.org and maybe have a duplicated one at fortran-lang.org/en? This way we don't need the additional redirect logic. Only thing to be careful about is that the language navigation works from both trees.

[henilp105]

@awvwgk , we can move the English language tree (language redirects can be handled in sphinx templates for languages) but the redirects of older webpage (jekyll) will conflict with the English language tree ( can we disable the older redirects for jekyll build ? ).

[awvwgk]

We can remove all redirects which are not needed anymore once the English tree is in the page door.

[certik]

I would remove all redirects and have the english page copied at fortran-lang.org/. It looks better anyway. This can be done with a script that runs after sphinx is finished.
