fix redirect on homepage

[tomkralidis]

When navigating to ​https://osgeo.org, I am redirected to ​https://www.osgeo.org/community/getting-started-osgeo/osgeo_userid/, which should instead have the same behaviour as navigating to ​https://www.osgeo.org/

I made a drastic change which hopefully doesn't break anything else. I change osgeo.org to go to wordpress container instead of osgeo.org. I think osgeo.org was used for multiple redirects. These should be resetup on wordpress container anyway if needed.

​https://git.osgeo.org/gitea/sac/osgeo7/commit/6d796797f1f179dff5aabf794672781f10a73187

so in osgeo7 nginx container

changed file etc/nginx/sites-available/osgeo.org:

                proxy_pass http://old-web.lxd:80/;

To:

		proxy_pass http://wordpress.lxd:80/;
