FEATURE: Append locale to links in crawler view if present (#34466)
This applies the following when
`SiteSetting.content_localization_enabled &&
SiteSetting.content_localization_crawler_param` and in crawler view.
- note: `content_localization_crawler_param` is an experimental site
setting
- attaches the following in crawler view, depending on the values in
`SiteSetting.content_localization_supported_locales`, assuming en, ja,
ko.
([old](https://developers.google.com/search/blog/2013/04/x-default-hreflang-for-international-pages)
but likely relevant)
```
      <link rel="alternate" href="https://nat-1.demo-by-discourse.com/" hreflang="x-default">
      <link rel="alternate" href="https://nat-1.demo-by-discourse.com/?tl=en" hreflang="en">
      <link rel="alternate" href="https://nat-1.demo-by-discourse.com/?tl=ja" hreflang="ja">
      <link rel="alternate" href="https://nat-1.demo-by-discourse.com/?tl=ko" hreflang="ko">
```
- appends the `tl` param based on the presence of it in the incoming
request
- this method puts every response for crawler requests through Nokogiri
parse.. so we'll have to see how this goes in practice
  
 ### Video
 
In the following video you can see each page has the code chunk above in
`head`, and each navigated page has the appropriate appended URL param.
