docs: Add note regarding phantom classes not being generated not being the end of the world
<div class="head">Phantom Resource</div>
<ul><li>Classes</li></ul>
<p>The phantom resource is used to store temporary class files that are generated to bolster things like recompilation and proper stack-frame generation.</p>
+ <p>If the phantom generation process fails, you may have to provide libraries as backing resources to use some features. But overall it should not be too big of a deal.</p>
<blockquote>
<p><strong>Note</strong>: This is regenerated each time a new workspace is created and runs in the background until completion.<br> It currently does not handle cases where generated methods belong to method hierarchies that get renamed.</p>
