    Update email template design and improve structure for better styling control (#62051)

    * Revert hardcoded email editor header font sizes

    * Wrap the WooEmailTemplate in a group block for easier style application.

    * Wrap the post-content block of the WooEmailTemplate in a group block for easier style application.

    * Update email template structure and adjust font size translations in tests

    - Wrap the post-content block in a group block for improved styling in the email template.
    - Modify font size translations for 'large', 'x-large', and add 'xx-large' in the Theme_Controller_Test.
    - Update content rendering tests to reflect changes in post-content block usage.

    * Prevent  `contentSize` not found error

    * Add changelog files

    * Unify post-content block lock settings by making sure the remover is disabled for the Woo Email Template.

    * Revert style h1 to h6 removal
