Prevent Trumbowyg from converting div to p element

[MikeAlhayek]

Fix #12049

From the semantic section in Trumbowyg docx

Since 2.12.0 you can also put an object to customize the semantic tag mapping for each one of these tags: <b>, <i>, <s>, <strike>, <div>.

The semantic option is set to true by default which is equivalent to:

$('.trumbowyg').trumbowyg({
    semantic: {
        'b': 'strong',
        'i': 'em',
        's': 'del',
        'strike': 'del',
        'div': 'p'
    }
});

To prevent the div from being converted into p we should set the semantic settings like this

$('.trumbowyg').trumbowyg({
    semantic: {
        'b': 'strong',
        'i': 'em',
        's': 'del',
        'strike': 'del'
    }
});

I don't agree to add these semantic options if they are already applied.
The idea is that the "Wysiwyg" editor option should not alter the "Tryumbowyg" editor default behavior.
This is why we have the "Trumbowyg" editor option that allows changing its behavior for your own needs.

semantic: false on Wysiwyg templates
Don't change anything on Trumbowyg templates
