Fix mentions to HTML to Platform Accessibility APIs Implementation Gu…

…ide (#3995)

The [HTML to Platform Accessibility APIs Implementation
Guide](https://www.w3.org/TR/html-aapi/) says "See [HTML Accessibility
API Mappings 1.0](https://www.w3.org/TR/html-aam-1.0/) instead".

So, this PR tries to replace to HTML-AAM or remove HTML-AAPI.

  <p>The objective of this technique is to describe the purpose of a link using the <code class="language-html">aria-label</code> attribute. The <code class="language-html">aria-label</code> attribute provides a way to place a descriptive text label on an object, such as a link, when there are no elements visible on the page that describe the object. If descriptive elements are visible on the page, the <code class="language-html">aria-labelledby</code> attribute should be used instead of <code class="language-html">aria-label</code>. Providing a descriptive text label lets a user distinguish the link from links in the Web page that lead to other destinations and helps the user determine whether to follow the link. In some assistive technologies the <code class="language-html">aria-label</code> value will show in the list of links instead of the actual link text.</p>
- <p>Per the <a href="https://www.w3.org/TR/accname/">Accessible Name and Description Computation</a> and the <a href="https://www.w3.org/TR/html-aapi/#accessible-name-and-description-calculation">HTML to Platform Accessibility APIs Implementation Guide</a>, the <code class="language-html">aria-label</code> text will override the text supplied within the link. As such the text supplied will be used instead of the link text by assistive technology. Due to this it is recommended to start the text used in <code class="language-html">aria-label</code> with the text used within the link. This will allow consistent communication between users.</p>

  <p>The concatenation of strings can be useful for different reasons. In example 1, an input is nested within the context of a full sentence. The desired screen reader output is "Extend time-out to [ 20 ] minutes - edit with autocomplete, selected 20". Since the <code class="language-html">id</code> of the text input is included in the string of <code class="language-html">id</code>s referenced by aria-labelledby, the value of the input is included in the concatenated name at the right position.</p>
  <p>Another application of <code class="language-html">aria-labelledby</code> is when there is no space to provide a visible label next to the input, or when using native labels would create unnecessary redundancy. Here, the use <code class="language-html">aria-labelledby</code> makes it possible to associate visible elements on the page as name for such inputs. This is demonstrated in example 2 where table column and row headings are concatenated into names for the text input elements inside the table.</p>
