fix(swift) - add proper syntax highlighting for class func/var declarations

[guuido]

Fixes the syntax highlighting for class functions and variables

Resolves #4121

Changes

Before the declaration of class func and class var was not handled correctly, for example

class func foo() async throws -> [Bar]
class var someProperty: Int { get }

was interpreted as

<span class="hljs-keyword">class</span> <span class="hljs-title class_">func</span> foo() <span class="hljs-keyword">async</span> <span class="hljs-keyword">throws</span> -&gt; [<span class="hljs-type">Bar</span>]
<span class="hljs-keyword">class</span> <span class="hljs-title class_">var</span> someProperty: <span class="hljs-type">Int</span> { <span class="hljs-keyword">get</span> }

After the fix the result is the following:

<span class="hljs-keyword">class </span><span class="hljs-keyword">func</span> <span class="hljs-title function_">foo</span>() <span class="hljs-keyword">async</span> <span class="hljs-keyword">throws</span> -&gt; [<span class="hljs-type">Bar</span>]
<span class="hljs-keyword">class </span><span class="hljs-keyword">var</span> someProperty: <span class="hljs-type">Int</span> { <span class="hljs-keyword">get</span> }
