Diffable Formatter Setting: Preserve whitespace in specific tags

[TheJaredWilcurt]

With this input:

<div>Hello World</div>
<a>Hello World</a>
<pre>Hello World</pre>

The following settings produce different results:

<!-- Default settings -->
<!-- global.vueSnapshots.formatting.tagsWithWhitespacePreserved = ['a', 'pre']; -->
<div>
  Hello World
</div>
<a>Hello World</a>
<pre>Hello World</pre>

<!-- global.vueSnapshots.formatting.tagsWithWhitespacePreserved = ['div']; -->
<div>Hello World</div>
<a>
  Hello World
</a>
<pre>
  Hello World
</pre>

<!-- Preserve whitespace in no tags with `false` or `[]` -->
<!-- global.vueSnapshots.formatting.tagsWithWhitespacePreserved = []; -->
<!-- global.vueSnapshots.formatting.tagsWithWhitespacePreserved = false; -->
<div>
  Hello World
</div>
<a>
  Hello World
</a>
<pre>
  Hello World
</pre>

<!-- Preserve whitespace in all tags with `true` -->
<!-- global.vueSnapshots.formatting.tagsWithWhitespacePreserved = true; -->
<div>Hello World</div>
<a>Hello World</a>
<pre>Hello World</pre>
