Delete the news page "HTTP/2 Server Push in Hugo"

See <https://answers.netlify.com/t/conditional-headers-based-on-user-agent/415/16>

Hey folks! Just wanted to mention that our product team has made a
decision not to ever support HTTP/2 server push, since Chrome is going
to deprecate it. We’ll focus on supporting HTTP/3 in the medium term
instead, since it will offer better performance gains.

-    As every page in Hugo can be output to multiple formats, it is easy to create Netlify's _redirects and _headers files on the fly.

-**Netlify** recently announced support for [HTTP/2 server push](https://www.netlify.com/blog/2017/07/18/http/2-server-push-on-netlify/), and we have now added it to the **gohugo.io** sites for the main `CSS` and `JS` bundles, along with server-side 301 redirect support.
-
-If you navigate to https://gohugo.io and look in the Chrome developer network console, you should now see `Push` as the new source ("Initiator") for the `CSS` and `JSS`:

-
-**Setting up this in Hugo was easy:**
-
-## 1. Configure Netlify Output Formats
-
-Add a new custom media type and two new output formats to `config.toml`. For more on output formats in Hugo, see [Custom Output Formats](/templates/output-formats/).
-
-```toml
-[outputs]
-home = [ "HTML", "RSS", "REDIR", "HEADERS" ]
-
-[mediaTypes]
-[mediaTypes."text/netlify"]
-suffix = ""
-delimiter = ""
-
-[outputFormats]
-[outputFormats.REDIR]
-mediatype = "text/netlify"
-baseName = "_redirects"
-isPlainText = true
-notAlternative = true
-[outputFormats.HEADERS]
-mediatype = "text/netlify"
-baseName = "_headers"
-isPlainText = true
-notAlternative = true
-```
-## 2. Add Template For the _headers File
-
-Add `layouts/index.headers`:
-
-```bash
-/*
-  X-Frame-Options: DENY
-  X-XSS-Protection: 1; mode=block
-  X-Content-Type-Options: nosniff
-  Referrer-Policy: origin-when-cross-origin
-*/
-  Link: <{{ "dist/app.bundle.js" | relURL }}>; rel=preload; as=script
-  Link: <{{ "dist/main.css" | relURL }}>; rel=preload; as=style
-```
-The template above creates both a security header definition and a HTTP/2 server push configuration.
-
-Also note that this is a template for the home page, so the full `Page` with its `Site` and many variables are available. You can also use `partial` to include other templates.
-
-
-## 3. Add Template For the _redirects File
-Add `layouts/index.redir`:
-```bash
-# Netlify redirects. See https://www.netlify.com/docs/redirects/
-{{  range $p := .Site.Pages -}}
-{{ range .Aliases }}
-{{  . | printf "%-35s" }}	{{ $p.RelPermalink -}}
-{{ end -}}
-{{- end -}}
-```
-The template above creates 301 redirects for your [aliases](/content-management/urls/#aliases), so you will probably want to turn off aliases in your `config.toml`: `disableAliases = true`.
