403 forbidden https://www.eclipse.org/membership/become-a-member/

During a call today, @scorbett brought to my attention that https://www.eclipse.org/membership/become-a-member/ is currently returning a 403.

Looking at our nginx config for the project, that URL should be redirecting to /membership/#tab-membership https://gitlab.eclipse.org/eclipsefdn/it/websites/eclipse.org/-/blob/main/config/nginx/default.conf?ref_type=heads#L132

location ~ ^/membership/become_a_member/\w*\.php$ {
      rewrite ^/membership/become_a_member/committer.php$ https://$host/membership/become-a-member/committer/ permanent;
      # match index.php and all subpages of become_a_member and redirect to
      # /membership/#tab-membership
      return 301 https://$host/membership/#tab-membership;
    }

@zacharysabourin Can you take a look, please? I suspect the issue is with the nginx config on the project not the top-level nginx instance since I can reproduce that error on some preview url.
