Twenty Twenty: ordered list styling in Classic Editor

[sabernhardt]

This issue was originally reported by @sebastienserre on GitHub:
​https://github.com/WordPress/classic-editor/issues/114

Twenty Twenty uses the square style for ordered lists when in the Classic Editor.

body#tinymce.wp-editor.content ol {
    margin-left: 1.5em;
    padding-left: 0;
    list-style: square;
}

In the main stylesheet, however, the style is set to list-style: decimal;

Sets Classic Editor's ol style to list-style: decimal;

Setting a milestone for this simple fix.

Of course, if someone wants to commit it sooner, I won't complain :)

Since the default value for list-style-type is decimal (for ol), wouldn't it suffice if we just remove list-style: square;?

[sabernhardt]

@hareesh-pillai The browser default might suffice for ordered lists, but this patch sets the editor styles to match the assigned front-end value.
​style.css, line 487

(If removing that from the editors' styles, it would not belong on the front end either.)

Thanks for the clarification, @sabernhardt
The attached patch looks good to me!
