Add photoswipe enroll class

Browse source 
`.photoswipe-images` 클래스를 가진 이미지는 강제로 포토스와이프가 적용됩니다.

```html
<a href="https://misol.kr/">
    <img class="photoswipe-images" src="https://example.com/something.jpg" />
</a>
```
와 같은 이미지는 포토스와이프가 적용됩니다.


```html
<a href="https://misol.kr/">
    <img class="photoswipe-images rx-escape" src="https://example.com/something.jpg" />
</a>
```
와 같은 상황에서도 포토스와이프가 적용됩니다.


```html
<a href="https://misol.kr/">
    <img class="rx-escape" src="https://example.com/something.jpg" />
</a>
```

와 같은 코드에서는 포토스와이프가 적용되지 않습니다.(`<a>` anchor 태그의 자식 요소, `rx-escape` 클래스가 있는 항목이기 때문)
