Enable alignment of diagrams using the text alignment buttons from the page-editor

[hbertsch]

Describe the feature you'd like

Currently only text and images react to the text alignment if I select left, right, center from the editor menu. A selected diagram is not responding to this and - by default - is always aligned to the left side of the page

Describe the benefits this would bring to existing BookStack users

• The user could intuitively use the alignment buttons to lay out diagrams on a page
• Instead of using a custom hack it would be possible to individually align diagrams on a page.
• The hack from https://github.com/BookStackApp/BookStack/issues/4463 is working, but only on a global level and will set the diagram alignment for all diagrams an all pages to the same value.

Can the goal of this request already be achieved via other means?

• Only with a global hack from https://github.com/BookStackApp/BookStack/issues/4463
