Add disclaimer slot to Checkout component

Introduced a new slot named "disclaimer" in the Checkout component to allow for additional user-defined content. Updated relevant files to demonstrate the usage of this new slot, enabling a flexible and modular design. This enhancement allows for the inclusion of important notices or legal disclaimers in the checkout process.
