Add :json type to auto_discovery_link_tag()

[veganstraightedge]

This is a feature request to support the new JSON Feed format in auto_discovery_link_tag.

See: https://jsonfeed.org/version/1#discovery

Steps to reproduce

Add an auto_discovery_link_tag using the type of :json

<%= auto_discovery_link_tag(:json, "https://example.com/feed.json", title: "JSON Feed" ) %>

Expected behavior

<link rel="alternate" title="JSON Feed" type="application/json" href="https://example.com/feed.json" />

Actual behavior

You should pass :type tag_option key explicitly, because you have passed json type other than :rss or :atom.

This meant I had to re-write like this:

<%= auto_discovery_link_tag(nil, "https://example.com/feed.json", { title: "JSON Feed", type: "application/json" }) %>

Bummer.

System configuration

Rails version: 5.1.0

Ruby version: 2.4.0

@bogdanvlviv @pixeltrix Can you give a reason why it was closed?

[pixeltrix]

@veganstraightedge because I merged #29158 which adds support for :json to auto_discovery_link_tag 😄

Oh thanks! I missed the merger PR. 👍🏻👍🏻👍🏻
