ADR 2.0.x wrong code block / indentation

[bwbroersma]

See DesignRules.md#L539-L549:

      <div class="example">
         <p>An example of a base path for an API with current version 1.0.2:</p>
         <pre>https://api.example.org/v1/</pre>
         <pre>version: '1.0.2'</pre>
         <pre>servers:
                  - description: test environment  
                  url: https://api.test.example.org/v1/  
                  - description: production environment  
                  url: https://api.example.org/v1/  
         </pre>
      </div>

The server part, and maybe version looks like a partial OpenAPI specification in YAML format, but currently it's incorrectly highlighted.
If it is indeed YAML it should be:

<pre class="yaml">YAML</pre>

Maybe version and server should be in one code block if it's indeed one YAML.

BTW YAML is supported by highlightjs.
