Titles are center aligned for pages using the Legacy Editor

Issue Summary

With the editing improvements for Confluence, pages are center-aligned, in line with the default's section of the editor. In the Legacy Editor, the titles are left-aligned and this has been recently changed to make the title be center-aligned as well, which no longer matches with the default editor's section/editor's body.

Steps to Reproduce

In Confluence, having the new editor already enabled for new pages, make sure to access a page using the Legacy Editor.

Expected Results

The title should be left-aligned, in line with the text and the editor's body.

Actual Results

The title is center-aligned as the model for the new editor experience.
