fix(wizard): align save button correctly when hideNavigation is true

[ljanner]

This fixes an edge case where hideNavigation is true and the previous/next buttons are hidden.

This can be tested with the wizard playground:

1. Open the wizard playground example
2. Disable Inline navigation
3. Disable Show previous/next buttons
4. Use the External navigation to go to the last step of the wizard

Code Review

This pull request fixes an alignment issue with the 'save' button in the wizard component when navigation buttons are hidden. My review includes a suggestion to extend this fix to also cover the edge case where there is only a single step in the wizard, which presents a similar alignment problem, ensuring the button is correctly positioned in both scenarios.

Changes:

• Add conditional end class to the footer Save button when hideNavigation() is true.
