feat(html): Add meta http-equiv attr page

[bsmth]

Description

additions:

• Dedicated page for the http-equiv attr.
• Sidebar entry

Changes:

• updates links from the DL meta#http-equiv to the page instead: meta/http-equiv

Motivation

There's a lot to say for this, there's too much info in the single DL, it warrants a separate page, exposing compat data.

The first sentence doesn't mean anything to me, and none of this says what it actually does. I think pragma doesn't mean much to developers who only work in JavaScript.

Can we do (something like):

Suggested change

	- : Defines a pragma directive, which are instructions for the browser for processing the document.
	The attribute's name is short for `http-equivalent` because the allowed values are names of equivalent HTTP headers.
	- : The `http-equiv` (short for `http-equivalent`) is used to specify a set of HTTP headers that the browser will apply to the document, as though they had been included in the response that returned the page.

	- : The `http-equiv` (short for 'HTTP equivalent') attribute tells the browser to behave as if the response that returned the page included certain HTTP headers.
	The values you can provide match the names of HTTP headers such as {{httpheader("Refresh")}} and {{httpheader("Content-Security-Policy")}}.

I had another go at this, what do you think?

Thanks @bsmth . I fixed a nit to my taste and this looks good to merge.
