refactor(web): move web engine help to app repo

Note: build.sh updated to make sure that test:help build action:target
doesn't also call test.sh by adding `:_all` meta-target.

Note: CI will need a new help-keyman-com.sh build step to deploy web
engine help.

Fixes: #12347

+title: Adding Keyboards
+---
+
+There are multiple ways to add and install keyboards into your KeymanWeb installation.
+
+In the examples that follow, please note the use of variable `kmw` as shorthand for the `keyman` object.
+
+## Directly linking a local copy
+
+The most efficient way to utilize a keyboard is to obtain a local copy of it and place this copy in a static location on your website. Once this is done, it can be directly linked into KeymanWeb as follows.
+
+```c
+keyman.addKeyboards({
+    id:'us',                  // The keyboard's unique identification code.
+    name:'English',           // The keyboard's user-readable name.
+    language:{
+      id:'en',                // A BCP 47 code uniquely identifying the language.
+      name:'English (US)'     // The language's name.
+    },
+    filename:'./us-1.0.js'    // A valid path to the compiled *.js file representing the keyboard.
+});
+```
+Custom fonts may also be utilized via the `language.font` property. For example:
+
+```c
+font:{
+    family:'LaoWeb',
+    source:['../font/saysettha_web.ttf','../font/saysettha_web.woff','../font/saysettha_web.eot']
+}
+```
+
+## Requested from the CDN by language name
+
+To obtain the default Keyman keyboard for a given language, call the following function.
+
+```c
+keyman.addKeyboardsForLanguage('Dzongkha');
+```
+
+This example would find the default keyboard for the Dzongkha language. This method will fail if the name doesn't perfectly match any language found in the CDN's repository.
+
+Alternatively, languages may be looked up via their BCP 47 language code as follows:
+
+```c
+keyman.addKeyboards('@he')
+```
+
+The `@` prefix indicates the use of the BCP 47 language code, which in this case corresponds with Hebrew.
+
+## Requested from the CDN by keyboard name
+
+To obtain a specific keyboard by name or by keyboard name and language code as a pair, see the following:
+
+```c
+keyman.addKeyboards('french','european2@sv','european2@no')
+```
+
+This will install three keyboards - one for French (named, quite simply, "French") and two copies of the EuroLatin2 keyboard - one for Swedish and one for Norwegian.

+
+This page shows how to include a local keyboard from an arbitrary location in your website's file structure.
+
+In this example, we use only the LaoKey keyboard. Please click [this link](./__auto-control.html) to open the test page.
+
+## Code Walkthrough
+
+```html
+<head>
+  <!-- Start of Code -->
+  <script src="js/keymanweb.js" type="text/javascript"></script>
+  <script>
+    window.addEventListener('load', function () {
+      keyman.init().then(function() {
+        keyman.addKeyboards({
+          id:'laokeys',
+          name:'Lao (Phonetic)',
+          languages:{
+            id:'lo',
+            name:'Lao'
+          },
+          filename:'./js/laokeys.js'
+        });
+      });
+    });
+  </script>
+  <!-- End of Code -->
+</head>
+```
+
+As you can see above, the second line in the code snippet above references the LaoKey keyboard loader JavaScript file. This is a small stub file, typically less than 200 bytes, that defines the name and actual location of the real keyboard file (in this case, **laokeys.js**). When a page may reference many keyboards, this saves downloading potentially hundreds of kilobytes of unused Javascript keyboards - the keyboard is downloaded when it is first selected by the user.
