Allow only one h1 tag on every page

@pouyamiralayi thanks as always for the huge support ❤️

BTW @ikenderham keep in mind that

editor.getComponents().filter(comp => comp.get('tagName') == tag).length > 1

is correct but only if need to check components as first children of editor.getComponents() (which returns children of the main wrapper)

If you need to check ALL components (including also nested children) you can use this

editor.getWrapper().find('h1').length > 1

@ikenderham

editor.on('component:add', component => {
            const tag = component.get('tagName')
            if (tag == 'h1') {
                if (editor.getComponents().filter(comp => comp.get('tagName') == tag).length > 1) {
                    component.remove()
                }
            }
        })

cheers!
