docs: Wrong information about the logo-* Ionicons

[iignatov]

The instructions for the logo-* icons (e.g. logo-javascript) on the Ionicons docs page are incorrect.

Currently the usage instructions (e.g. for logo-javascript) are:

  <!--Basic: auto-select the icon based on the platform -->
  <ion-icon name="javascript"></ion-icon>

  <!-- Advanced: explicity set the icon for each platform -->
  <ion-icon ios="logo-javascript" md="logo-javascript"></ion-icon>

but instead they should be:

  <!--Basic: auto-select the icon based on the platform -->
  <ion-icon name="logo-javascript"></ion-icon>

  <!-- Advanced: explicity set the icon for each platform -->
  <ion-icon ios="logo-javascript" md="logo-javascript"></ion-icon>

or even better (because the name is the same for all platforms):

  <ion-icon name="logo-javascript"></ion-icon>

The title should also display the full icon name, i.e. logo-javascript instead of javascript (currently).

Additionally it would be great if these icons (i.e. logo-*) are displayed in all columns in the table view, because currently it looks as if they are available only for iOS.

Looks like the actual template for the modal may need to change
