Can't create or select new templates for lessons in non-block themes.

[Imran92]

Steps to Reproduce

1. Install or make sure you are on a non-block/FSE theme like twenty twenty one or Astra
2. Go to a lesson
3. From the settings panel on right, create a new template
4. click on Update

What I Expected

To save without issue

What Happened Instead

You see an error message saying The update failed. Invalid parameter(s): "template"

I've already done some investigation. Looks like it happens only on non-block and non-fse themes. If you use block themes, like twenty twenty three or Course, this issue doesn't happen

Is there any update on this? We are also running into this issue trying to transition lessons within a course to a new layout but unable to switch from the default lesson template to facilitate the change.
