Added anchor without link to internalparsertest

[tyson-nw]

Sorry if this is the wrong way to do this, it is my first pull request on a project I don't own.

Basically, the functionality I am looking for is when an internal link only includes the anchor, in the case of [[#anchor]] or [[#anchor|title]] that it creates an anchor link that points to an anchor in the current page. Used in conjunction with League\CommonMark\Extension\HeadingPermalink\HeadingPermalinkExtension it should allow you to link to heading anchors within the page.

I am unsure how to write that myself, so I added the tests that would check for it.

@tyson-nw I've pushed a change to this PR that appears to satisfy the test. Let me know if it works for you; if so, I'll merge it and tag a new release.

It is still not parsing anchor links. For example, this bit of markdown

## Rolls
When you "make a roll" you roll a [[#d12]] and add a bonus. The bonus is the total of the [[#Stat]] being used for the roll, the [[#Skill]] being used for the roll, and any [[#Specialty]] that the [[#Game Master]] agrees applies. Then you compare the roll to the [[#Target Number]], if it is higher the roll succeeds. If the roll is lower or equal to the [[#Target Number]], the roll fails.

It is producing

<h2><a id="content-rolls" href="#content-rolls" class="heading-permalink" aria-hidden="true" title="Permalink"></a>Rolls</h2>
<p>When you &quot;make a roll&quot; you roll a [[#d12]] and add a bonus.

Then you compare the roll to the [[#Target Number]], if it is higher the roll succeeds. If the roll is lower or equal to the [[#Target Number]], the roll fails.</p>

instead of

<h2><a id="content-rolls" href="#content-rolls" class="heading-permalink" aria-hidden="true" title="Permalink"></a>Rolls</h2>
<p>When you &quot;make a roll&quot; you roll a <a href='#content-d12'>d12</a> and add a bonus. The bonus is the total of the <a href='#content-stat'>Stat</a> being used for the roll, the <a href='#content-skill'>Skill</a> being used for the roll, and any <a href='#content-specialty>Specialty</a> that the <a href='#content-game-master'>Game Master</a> agrees applies. Then you compare the roll to the <a href='#content-target-number'>Target Number</a>, if it is higher the roll succeeds. If the roll is lower or equal to the <a href='#content-targer-number'>Target Number</a>, the roll fails.</p>

I am using the use League\CommonMark\Environment\Environment; config with the use League\CommonMark\Extension\HeadingPermalink\HeadingPermalinkExtension; and use League\CommonMark\Extension\HeadingPermalink\HeadingPermalinkRenderer;

$config = [
            'heading_permalink' => [
                'html_class' => 'heading-permalink',
                'id_prefix' => 'content',
                'fragment_prefix' => 'content',
                'insert' => 'before',
                'min_heading_level' => 1,
                'max_heading_level' => 6,
                'title' => 'Permalink',
                'symbol' => "",
            ],
];
