feat(cassettator-markers): css customization

Facilitates customization via CSS. It is no longer necessary to target the
component class in order to redefine the CSS variable, thus improving the
developer experience.

In concrete terms, this means the following changes:

- Before modification:
  ```css
    .cst-marker {
        --cst-marker-played-background-color: blue;
    }
  ```
- After modification:
  ```css
    .video-js {
        --cst-marker-played-background-color: blue;
    }
  ```

- remove the assignment of a default value to variables
- add a new variable for the default background color
- add documentation for the new variable
