feat: order docs page by weight
Fixes a previous issue where Installation wasn't showing up first
<!-- only show pages where dir is the same as the _index.md -->
{{ $pages := .Sections }}
{{ $pages := union $pages (where .Site.RegularPages ".File.Dir" $parentDir )}}
- {{ range $pages}}
+ {{ range $pages.ByWeight}}
<div class="col col-4 item">
<h4><a href="{{ .Permalink }}">{{ .Title }}</a></h4>
