[2.x] Update default configuration to no longer save previewed pages

[emmadesilva]

PR Description: Implement Changes to Serve Command

This pull request addresses issue #1994 by updating the serve command to not save pages by default. This change aims to enhance the developer experience by making the behavior of the serve command less unexpected.

Motivation for the Change

• Unexpected Behavior: The current implementation of the serve command saves pages by default, which can be surprising for developers who do not anticipate this action.
• Improved Development Workflow: By not saving pages by default, the development workflow becomes more intuitive, allowing developers to preview changes without automatically persisting them.

Key Changes

• Update the serve command to disable automatic saving of pages by default.
• The option for users to enable saving if desired is still available.

This PR fixes #1994
