hotfix(media): Simplify removeCSSClass method

This commit simplifies the `removeCSSClass` method in the
`MediaComponent` by removing the commented code and consolidating
the removal of the CSS class from the `body` and `ion-app` elements
in a single conditional block. The method now checks for the
existence of the `body` and `ion-app` elements before attempting to
remove the CSS class, ensuring a more concise and efficient
implementation.
