Accessibility Issue with Course Title Block hardcoded as H2 Tag

[richardlhr]

Resolves #

Proposed Changes

• Allow to change the Heading type (H1, H2,... H6) as having a hardcoded H2 Heading in the Header is not ADA compliant

Testing Instructions

1. In the Admin UI, navigate to Sensei LMS > Settings > Appearance
2. Click on the Customize Button of the Default Learning Mode Template
3. Click on Sensei LMS Templates and then click on the Lesson Template
4. In the Header, select the Course Title Block
5. You should be able to see a "Change Level" setting defaulting to H2. Select H1
6. On the Right hand side, it is not possible to also change Typography, Dimensions and add additional CSS class (Advanced) as to match the Course Progress Counter Block
7. Save
8. On the frontend, go to a course, navigate to the lesson and check the the Course Title has the correct tag and style.

Hello, and thanks for the PR! I took this for a quick test drive and here's what I found:

• Right now the text is editable but shouldn't be. Even if you try adding custom text, it's overridden when you change the level or view it on the frontend.
• Also, would you kindly clarify what you mean by the following. Did you mean to say that it is possible to change these things?

On the Right hand side, it is not possible to also change Typography, Dimensions and add additional CSS class (Advanced) as to match the Course Progress Counter Block
